SUMMARY:Alexander Stibor (LBNL) "QIS with Coherent Electrons: Quantum Sensors\, Superconducting Emitters\, Signal Transmission and Decoherence Studies"
DESCRIPTION:Abstract:  \nCreating\, manipulating and detecting coherent\, entangled quantum states and isolating quantum systems from decoherence is at the heart of future quantum information science technologies. With the rise of novel instruments in quantum electronics\, the coherent emission and control of free electron beams become relevant in various fields of physics. In this presentation\, I will give an overview of the research performed in Tuebingen (Germany) and at the LBL Molecular Foundry where we are currently realizing the QUINTESSENCE QIS project. The aim is to use the matter-waves of electrons\, superconductivity and correlation detection to develop novel quantum techniques and applications in sensor technology\, electron microscopy and signal transmission. Such experiments are demonstrated with a biprism electron interferometer. We realized a correlation sensor for electromagnetic and vibrational perturbations and a secure signal transmission method by matter-wave modulation. Furthermore\, I will present a characterization setup for a superconducting niobium nano-tip field emitter. This beam source has the potential to emit entangled electron pairs that open up new modes in quantum information\, quantum metrology and electron spectroscopy. To achieve long coherence times in future quantum instrumentation\, a basic understanding of decoherence\, being the transition from a quantum to a classical state\, is crucial. We studied experimentally the Coulomb-induced decoherence of electrons in a superposition state and were able to rule out three of four current theoretical approaches in the literature. It allows the development of novel non-invasive techniques for quantum electron microscopy.http://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94679537616 \nMeeting ID: 946 7953 7616\nOne tap mobile\n+16699006833\,\,94679537616# US (San Jose)\n+12532158782\,\,94679537616# US (Tacoma) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 946 7953 7616\nFind your local number: https://lbnl.zoom.us/u/abKfGWf6S \nJoin by SIP\n94679537616@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 946 7953 7616 \n──────────

SUMMARY:Alex Kim (LBNL)"Opportunities for Peculiar Velocity Surveys Using DESI\, ZTF-II\, and the Vera C. Rubin Observatory"
DESCRIPTION:ABSTRACT: \nThe motions of galaxies on top of the Hubble expansion\, peculiar velocities\, are a probe of clustering and the growth of structure in the Universe.  For distance indicators\, peculiar velocities manifest themselves as residuals on the Hubble diagram.  Ongoing and upcoming wide-field surveys measuring unprecedented numbers of distance indicators\, together with improvements in the calibration of Type Ia supernova brightnesses\, will provide exquisite precision in the mapping of the peculiar velocity field or more precisely the peculiar distance field.  LBL is well positioned to make distance measurements of sources from DESI\, the Zwicky Transient Facility (ZTF)\, ZTF-II\, and the Rubin Observatory in order to produce compelling constraints on the laws of gravity responsible for the growth of structure. \n  \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Daniel Carney (U. Maryland) "Fundamental Physics at the Quantum Limits of Measurement
DESCRIPTION:Abstract:\n40 years ago\, Caves\, Thorne\, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a gravitational wave by LIGO in 2016. I will review these types of quantum limits and discuss their application to particle physics. In particular\, I will present some new dark matter detection ideas which leverage quantum sensing and control of massive opto-mechanical systems. Current experiments with these devices are already capable of ruling out some exotic dark matter candidates\, and I will focus on these and their next-generation extensions. I will also present some much longer-term applications: a scheme for direct detection of heavy dark matter purely through gravity\, and tabletop experiments testing the quantum nature of gravity.\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96617590466 \nMeeting ID: 966 1759 0466\nOne tap mobile\n+16465588656\,\,96617590466# US (New York)\n+16699006833\,\,96617590466# US (San Jose) \nDial by your location\n+1 646 558 8656 US (New York)\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 346 248 7799 US (Houston)\nMeeting ID: 966 1759 0466\nFind your local number: https://lbnl.zoom.us/u/ackakuVouX \nJoin by SIP\n96617590466@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 966 1759 0466 \n──────────

SUMMARY:Rakshya Khatiwada (Fermilab)   "Hunting for Dark matter using quantum devices and sensors"
DESCRIPTION:Rakshya Khatiwada (Fermilab) \n“Hunting for Dark matter using quantum devices and sensors”\n\n \nAbstract:\n\nVery few mysteries in our current picture of the universe are bigger than the puzzle of dark matter. Recently the QCD axion — a weakly interacting\, sub-eV particle — has been in the limelight as a cold dark matter candidate which also enjoys compelling theoretical motivation as a possible solution to the strong CP problem. This talk will give an overview of modern axion searches with a detailed discussion of the role of quantum devices and technology in the most sensitive axion experiment to date. Furthermore\, it will discuss promising novel methods of axion searches using quantum sensors as single photon counters that could make possible the investigation of axions in previously uncharted mass ranges. \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91908754680\n\nMeeting ID: 919 0875 4680\nOne tap mobile\n+16699006833\,\,91908754680# US (San Jose)\n+12532158782\,\,91908754680# US (Tacoma)\n\nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 919 0875 4680\nFind your local number: https://lbnl.zoom.us/u/aba1991Le\n\nJoin by SIP\n91908754680@zoomcrc.com\n\nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 919 0875 4680\n\n──────────

SUMMARY:Stephen Gourlay (LBNL) "Snowmass 2021: Survey of Potential Collider Options"
DESCRIPTION:ABSTRACT: \n\n\nWe are now approximately 3 months into the next Snowmass process and a plethora of ideas is starting to surface. Technical maturity of the proposed facilities ranges from shovel ready to those that are still largely conceptual. Developments in accelerator technology since the last Snowmass could increase the number of feasible ideas for P5 to consider. This talk will give a brief summary of some of the collider options; current status\, technical readiness level and challenges\, that we expect to see coming out of the current planning process. \n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Beate Heinemann (DESY) "European Strategy for Particle Physics Update 2020"
DESCRIPTION:Abstract:  \nI will present the updated European strategy for particle physics which was announced by the CERN Council in June. The strategy was developed in a process that spanned two years and engaged both the European and the international community of particle physics\, as well as related scientific disciplines. The highest-priority physics recommendations are the study of the Higgs boson and the exploration of the high-energy frontier: two crucial and complementary ways to address the open questions in particle physics. Questions related to the dark universe\, flavor and other puzzles of the Standard Model are also discussed. Finally\, technological and societal challenges and opportunities are also highlighted. \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Kyle Dawson (U. Utah) "The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Cosmological Implications from two Decades of Spectroscopic Surveys at the Apache Point observatory"
DESCRIPTION:Abstract: \nThe Extended Baryon Oscillation Spectroscopic Survey (eBOSS) concluded observations of the cosmic distance scale and the growth of structure in February\, 2019.  The three dimensional clustering in all samples from the Sloan Digital Sky Survey (SDSS) was used to make 15 distinct\, high precision measurements of Baryon Acoustic Oscillations (BAO) to an effective redshift z<2.4 and six measurements of redshift space distortions (RSD) to z<1.5.  With this redshift coverage and sensitivity\, the SDSS experiment is unparalleled in its ability to explore models of dark energy.  Using available cosmological samples\, we provide new constraints on the cosmological model with an emphasis on the role of the final BAO and RSD clustering measurements in advancing the cosmological model.  In this talk\, I will give a brief overview of the BAO and RSD measurements and present the highlights of the advances in modeling dark energy\, the local expansion rate\, tests of general relativity\, neutrino masses\, and the overall cosmological model.\n  \n  \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n────────── \n

SUMMARY:Zara Bagdasarian (UCB) "Solar Neutrinos with Borexino: First Evidence of CNO Fusion Cycle"
DESCRIPTION:Abstract:\nThe prime energy producer in the sun is the fusion of hydrogen to form\nhelium. However\, there is more than one way for this fusion to take\nplace: for stars the size of the sun or smaller\, the proton-proton (pp)\nchain reactions dominate (~99%)\, while in heavier stars\, the\ncarbon-nitrogen-oxygen (CNO) cycle is expected to play a more important\nrole. Not only these fusion reactions would not have been possible\nwithout the emission of neutrinos\, neutrinos are the only way to\ndirectly access the processes in the core of the sun. \nBorexino experiment\, located at the Laboratori Nazionali del Gran Sasso\,\nwas built with a primary goal of the Be7 solar neutrinos (part of pp\nchain) detection. In more than a decade of data taking\, Borexino has not\nonly demonstrated the unprecedentedly high sensitivity towards Be7 solar\nneutrinos (<3%) but performed a comprehensive study of low-energy\nneutrinos from the complete pp-chain. After a number of developments in\nboth hardware and software\, Borexino presents the first experimental\nevidence of the up-to-now elusive CNO fusion cycle in the Sun. The\nabsence of the CNO neutrinos signal is disfavoured by the Borexino\nexperiment at 5σ. \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:JOINT INPA/RPM Seminar | Michelle Galloway (University of Zurich) "Observation of excess electronic recoil events in XENON1T"
DESCRIPTION:Abstract:  \nA search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region\, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs\, 3.2 sigma for an enhanced neutrino magnetic moment\, and 3.0 sigma global (4.0 local) for bosonic dark matter with a peak at 2.3 +- 0.2 keV (68% C.L.). Additionally\, a previously undetected tritium component\, favoured at 3.2 sigma over known backgrounds\, can neither be confirmed nor excluded. I will provide an overview of the XENON1T detection and analysis methods for this search\, a characterization of the excess events\, and present results for both possible backgrounds and potential new physics. \nhttps://lbnl.zoom.us/j/98002426771?pwd=R3dtTFhmb0ZyR0ZHV1E5amZCcnFBZz09 \nMeeting ID: 980 0242 6771\nPassword: 531232

SUMMARY:Josh McFayden (LBNL) "Unravelling LEP-Era Lepton Flavour Universality Discrepancy with ATLAS"
DESCRIPTION:Abstract:  \n\nA remarkable feature of the Standard Model (SM) is that each lepton flavour (electron\, muon\, tau) is equally likely to interact with a W boson. This is known as Lepton Flavour Universality. \n\n\nIn a recent ATLAS measurement\, a novel technique using events with top-quark pairs has been exploited to test the ratio of the probabilities for tau leptons and muons to be produced in W boson decays\, R(τ/μ). \n\n\nIn the SM\, R(τ/μ) is expected to be unity\, but a longstanding tension with this prediction has existed since the LEP era\, where\, from a combination of experiments\, R(τ/μ) was measured to be 2.7σ higher than the SM expectation. \n\nIf the LEP result were confirmed to O(1%) precision it would correspond to an unambiguous discovery of beyond the SM physics. This latest ATLAS measurement obtains this level a precision – please join the RPM to discover whether or not it agrees with LEP!\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95906405235 \nMeeting ID: 959 0640 5235\nOne tap mobile\n+16699006833\,\,95906405235# US (San Jose)\n+13462487799\,\,95906405235# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 959 0640 5235\nFind your local number: https://lbnl.zoom.us/u/a9dnGtb5T \nJoin by SIP\n95906405235@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 959 0640 5235 \n──────────

SUMMARY:Yacine Ali-Haimoud (NYU) "Hunting for Dark Matter in the Early Universe"
DESCRIPTION:ABSTRACT:\n\n\n\nIt is now well established that the dominant part of non-relativistic matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter remains a nagging puzzle\, and several candidates remain in the running. For instance\, dark matter might be a new particle\, as light as an electron\, which might weakly interact with standard particles. Or it could be partly made of primordial black holes as massive as many Suns\, born in the very early Universe from the gravitational collapse of enhanced primordial fluctuations. In this talk\, I will describe how one can try and tease out some of the properties of dark matter from the Cosmic Microwave Background (CMB)\, both through its frequency spectrum\, and its angular fluctuations. After reviewing the basic physics underlying the CMB\, I will highlight how it can constrain interacting particles and primordial black holes. If time allows\, I will discuss what LIGO may be able to tell us about primordial-black holes.\n\n\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Vivian Miranda (U. Arizona) "The Connected Universe: Relating Early\, Intermediate and Late Universe with cosmological data"
DESCRIPTION:Abstract:\nThe standard model of cosmology is built upon on a series of propositions on how the early\, intermediate\, and late epochs of the Universe behave. In particular\, it predicts that dark energy and dark matter currently pervades the cosmos. Understanding the properties of the dark sector is plausibly the biggest challenge in theoretical physics. There is\, however\, a broad assumption in cosmology that the Universe on its earlier stages is fully understood and that discrepancies between the standard model of cosmology and current data are suggestive of distinct dark energy properties. Uncertainties on this hypothesis’s validity are not usually taken into account when forecasting survey capabilities\, even though our investigations might be obfuscated if the intermediate and early Universe did behave abnormally. In this colloquium\, I propose a program to investigate dark energy and earlier aspects of our Universe simultaneously\, through space missions in the 2020s in combination with ground-based observatories. This program will help guide the strategy for the future Rubin and Roman supernovae and weak lensing surveys. My investigations on how properties of the early and intermediate Universe affect inferences on dark energy (and vice-versa) will also support community understanding of how future missions can be employed to test some of the core hypotheses of the standard model of cosmology.\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Nan Lu (Caltech) "Evidence for Higgs Boson Decay to a Pair of Muons from the CMS Experiment "
DESCRIPTION:Abstract:\n\nThis seminar presents the search for the rare Higgs boson decay to a pair of muons performed by the CMS experiment at the LHC\, based on the full Run 2 dataset. Events are categorized based on the characteristics of major Higgs boson production mechanisms and are analyzed using machine learning techniques\, which significantly boosts the sensitivity of the search. A 3.0σ excess is observed in data\, constituting the first evidence for the Higgs boson coupling to muons. \n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Andrej Obuljen (Waterloo) "Anisotropic Assembly Bias in Theory\, Simulations and BOSS Data"
DESCRIPTION:ABSTRACT\nClustering of matter on large scales provides an important source of information on key cosmological parameters. To extract this information we need to understand the relation between the tracers we observe and the underlying matter field. The clustering strength of halos and galaxies on large scales is linearly biased compared to the matter clustering. This linear bias mainly depends on halo mass and redshifts\, though selections based on other scalar halo properties (age\, spin\, concentration etc.) show additional bias dependences — called assembly bias. Furthermore\, non-scalar halo properties: shapes\, velocity dispersion and angular momentum\, are correlated with the large-scale tidal field. Selection effects that couple to these non-scalar halo properties can produce anisotropic clustering even in real-space and act as a contaminant to redshift-space distortion measurements\, through an anisotropic assembly bias (AB). I will discuss our recent results on studying the halo AB using a large number of numerical simulations. Then I will present the first detection of the galaxy anisotropic assembly bias in BOSS DR12 galaxies. Finally\, I will show other consequences and future prospects. \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Simone Pagan-Griso (LBNL) "The Future of the Energy Frontier: Highlights from the Snowmass 2021 Process"
DESCRIPTION:Abstract: \nThe Snowmass process is an opportunity for the entire HEP community to come together to identify and document a vision for the future of particle physics in the U.S. and its international partners. The Snowmass 2021 process is currently ongoing and scheduled to deliver a report in the fall of 2021. The work is divided in many areas (frontiers)\, spanning collider-based physics\, neutrino physics\, and cosmology\, but including dedicated theory and instrumentation areas as well.\nIn this seminar\, I will focus on highlighting some of the ideas and plans that have been forming in the area of the energy frontier\, with particular focus on prospects for direct searches of Beyond-Standard-Model physics; I will also discuss some synergies with other areas\, when relevant.

SUMMARY:Hannsjörg Weber (FNAL) "Triple Threat: The Observation of Tribosons "
DESCRIPTION:Hannsjörg Weber \nTriple Threat: The observation of tribosons \nAbstract: \nWe present the search for heavy triboson production\, specifically targeting the production of WWW\, WWZ\, WZZ and ZZZ processes in multileptonic final states with 137/fb of data collected by the CMS detector during Run II of the LHC at a center-of-mass energy 13 TeV.  The search is performed in final states with three\, four\, five\, and six leptons (electrons or muons)\, or with two same-charge leptons plus two jets. \nDuring this seminar\, the physics behind the triboson process will be motivated\, including a discussion on the difficulties to experimentally measure it. Then\, the analysis strategy aimed to observe tribosons will be shown and the results will be presented. At the end\, an outlook on future triboson studies and extensions towards probing the standard model and potential new physics will be given. \n \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95906405235 \nMeeting ID: 959 0640 5235\nOne tap mobile\n+16699006833\,\,95906405235# US (San Jose)\n+13462487799\,\,95906405235# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 959 0640 5235\nFind your local number: https://lbnl.zoom.us/u/a9dnGtb5T \nJoin by SIP\n95906405235@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 959 0640 5235 \n──────────

SUMMARY:Donatella Lucchesi (INFN) ""Muon Collider: A Window to the Future""
DESCRIPTION:Abstract:\n \nMuon colliders represent a highly attractive option for future collider thanks to the possibility to reach very high center of mass energy\, high luminosity with reasonable costs and dimensions. Nevertheless\, the feasibility is not yet fully demonstrated and presents several challenges: muon beams production and operations from the machine side and beam-induced background mitigation on the detector part. Several progress have been achieved in the last years allowing to re-open the muon collider case. The detailed study of the beam-induced background has demonstrated that even the most challenging events like those involving b-jets can be efficiently reconstructed. This has triggered the study of several Higgs related processes in particular the double and triple Higgs production with sufficient precision to fully determine the Higgs potential. In the seminar a brief description of the machine will be followed by a discussion on the performance on detector and Higgs reconstruction. \n \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Jesse Thaler (MIT) "The Hidden Geometry of Particle Collisions"
DESCRIPTION:ABSTRACT:\n\nIn this talk\, I explain how various concepts and techniques in quantum field theory and collider physics can be naturally translated into a new geometric language. Using the energy mover’s distance\, which quantifies the minimal amount of “work” required to rearrange one event into another\, we can define a distance between pairs of collider events.  This distance can then be used to triangulate the “space” of collider events and rigorously define various geometric objects.  Many well-known collider observables\, jet algorithms\, and pileup mitigation schemes have a simple geometric interpretation\, as does the important concept of infrared and collinear safety.  Intriguingly\, these ideas can be lifted from a distance between events into a distance between theories\, with potential relevance for visualizing and interpreting data from the LHC.\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Matt Klein (Michigan) "Search for Higgs boson decays to bottom quarks in the vector boson fusion production mode"
DESCRIPTION:ABSTRACT:\nThe Higgs boson is expected to decay to bb approximately 58% of the time. Despite the large branching fraction\, due to the large background from SM events with b-jets\, measuring this decay has been less precise than other\, less frequent\, decays. Measuring H(bb) in the VBF production mode has historically been insensitive\, but developments in the background estimates and discrimination\, as well as improvements in the signal extraction techniques\, have resulted in an observed (expected) significance of 3.0 (3.0) standard deviations from the background-only hypothesis using the LHC Run 2 dataset. \n \nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n──────────

SUMMARY:Zhicai Zhang (CalTech) "Search for Long-Lived Particles with Precision Timing Detectors"
DESCRIPTION:Abstract:\nSearching for new physics beyond the standard model (BSM) has been one of the main goals of the LHC. With no new physics found in many SUSY and Exotica searches for prompt BSM particles from the LHC data\, I will present a new BSM search approach that is looking for new particles with a long lifetime. The search is looking for SUSY long-lived particles that decay to photons\, with the final state photon being time-delayed compared to prompt photon background. The search relies on the precise measurement of the photon arrival time at the calorimeter\, and I will present the study of the timing performance of current CMS ECAL\, and also developments of future precision timing detectors to be installed for CMS Phase 2 upgrade as well as precision timing detectors for future experiments.\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.

SUMMARY:Aniruddha Bapat (University of Maryland\, College Park)   "Variational Quantum Optimization in the NISQ Era"
DESCRIPTION:ABSTRACT:\n\nQuantum information science in the coming decade will likely be carried out on noisy devices consisting of ~100-1000 qubits that do not share full interconnectivity. In this so-called NISQ regime\, variational quantum algorithms\, which tackle a wide range of problems from areas such as combinatorial optimization\, quantum chemistry\, and high-energy physics\, provide a path to practical quantum advantage. In this talk\, I will present some of our recent work that explores the theory behind variational algorithms such as quantum annealing and quantum approximate approximation algorithm (QAOA) using tools from optimal control theory. Then\, I will discuss our work on finding the ground state of a critical Ising model on a trapped-ion quantum simulator\, and the underlying optimization strategy. Finally\, I will mention applications of our ideas and upcoming work.\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/93701922305 \nMeeting ID: 937 0192 2305\nOne tap mobile\n+16699006833\,\,93701922305# US (San Jose)\n+13462487799\,\,93701922305# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\nMeeting ID: 937 0192 2305\nFind your local number: https://lbnl.zoom.us/u/abZEZ2imIY \nJoin by SIP\n93701922305@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 937 0192 2305 \n──────────

SUMMARY:Michael Kreshchuk (Tuft University) "Quantum simulation of relativistic field theories in the front form"
DESCRIPTION:Abstract: \nI will talk about quantum simulation algorithms based on the light-front formulation of quantum field theory. They will range from\nab initio simulations with nearly optimal resource scalings to VQE-inspired methods available for existing devices.My work is greatly inspired by the analogy\, first noted by Kenneth Wilson\, between the light-front formulation of QFT and quantum\nchemistry. The approach I develop to simulating field theory is an alternative to lattice techniques; it allows one to use methods\ndeveloped for quantum simulation of quantum chemistry.\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91625177639 \nMeeting ID: 916 2517 7639\nOne tap mobile\n+16699006833\,\,91625177639# US (San Jose)\n+13462487799\,\,91625177639# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\nMeeting ID: 916 2517 7639\nFind your local number: https://lbnl.zoom.us/u/adsFO9iBos \nJoin by SIP\n91625177639@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 916 2517 7639 \n──────────

SUMMARY:Xinran Li (Princeton University)    "The energy resolution and the energy deposition processes in noble liquid dark matter detectors"
DESCRIPTION:Abstract: \n\nNoble liquid detectors\, especially liquid argon and liquid xenon time projection chambers (TPCs) have been developed and improved during the last decades. They produced the best limits in the search for one of the best motivated dark matter candidates\, weakly interacting massive particles (WIPMs)\, in the O(10)GeV to O(10)TeV mass region. I’ll first talk about the DarkSide-50 low mass analysis which produced the best limit of 5$\times$10^{-42} cm^2 on spin-independent dark matter nuclear scattering cross section for dark matter masses around 3 GeV. The detector energy resolution around the analysis threshold strongly affects the shape of the limit curve in the low mass region. One main contribution to the energy resolution comes from the intrinsic fluctuations during the energy deposition processes\, including the quenching processes and the charge recombination\, in noble liquids. Extending to different materials\, I’ll also mention the scintillation in xenon doped liquid argon\, and the recombination in amorphous selenium. The energy resolution can be improved with sensitivity to the quenched heat energy. Superfluid helium 4 detectors have been proposed to probe nuclear recoil dark matter masses as low as O(10)MeV with current technology. The compatibility with phonon sensors permits sensitivity to all energy deposition channels in superfluid helium.\n  \n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/92548118001 \nMeeting ID: 925 4811 8001\nOne tap mobile\n+16699006833\,\,92548118001# US (San Jose)\n+13462487799\,\,92548118001# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 925 4811 8001\nFind your local number: https://lbnl.zoom.us/u/aebrpK1L6a \nJoin by SIP\n92548118001@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 925 4811 8001 \n──────────

SUMMARY:Dylan Temples (Northwestern University)  New Directions in Liquid Noble Dark Matter Searches: Probing the Sub-GeV Regime
DESCRIPTION:Abstract: \n\nThe most sensitive searches for dark matter (DM) with mass above ~10 GeV/c2 use the dual-phase xenon time-projection chamber (LXe-TPC) technology. In the U.S.\, development of this technology is spearheaded by the LUX-ZEPLIN experiment\, with first science data coming soon. As these detectors increase in scale and sensitivity\, previously negligible backgrounds become important to understand\, both to prevent false discovery claims and to accurately measure the ultimate DM sensitivity of such an experiment. In this talk\, I will discuss one class of such backgrounds: neutrinos scattering from the inner-shell electrons of a xenon atom. This process has heretofore gone uncalibrated\, and due to its distinct event topology\, is more akin to a nuclear recoil (potential DM signal) than an electron recoil (background). I will also discuss two liquid-noble technologies for searching for dark matter below ~5 GeV/c2: light-element doping\, and superfluid helium detectors. Doping an LXe-TPC with low concentrations of light elements\, such as hydrogen\, enables sensitivity to dark matter models with mass down to 20 MeV/c2 while simultaneously probing spin-dependent DM-nucleon coupling. Superfluid helium detectors offer a complementary DM search avenue\, as it is more sensitive to low-mass spin-independent DM than hydrogen-doping\, but cannot investigate spin-dependent coupling.\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98616683565 \nMeeting ID: 986 1668 3565\nOne tap mobile\n+16699006833\,\,98616683565# US (San Jose)\n+13462487799\,\,98616683565# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 986 1668 3565\nFind your local number: https://lbnl.zoom.us/u/aeitM56qYB \nJoin by SIP\n98616683565@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 986 1668 3565 \n──────────

SUMMARY:Digvijay Wadekar (New York University) "Accelerating analysis of cosmological surveys with novel analytic methods and machine learning"
DESCRIPTION:– Abstract: \n\nIn order to infer cosmological parameters from data of upcoming surveys like DESI\, we will use summary statistics such as the power spectrum. An accurate estimate of their covariance matrix is crucial for the inference analysis. The traditional process of obtaining the covariance involves thousands of expensive mock simulations. I will present a novel analytic approach to calculate the covariance which is faster by more than four orders of magnitude. I will demonstrate the validation of our analytic approach with an analysis of the BOSS DR12 data and also show that it helps reduce the systematic error budget of cosmological constraints\, thus making our approach useful for upcoming high-precision surveys like the Rubin observatory and DESI. \n \nIn the second part of my talk\, I will present machine learning methods to emulate expensive hydrodynamical simulations and make cheap and accurate synthetic catalogs\, which are needed for modeling non-linear scales in galaxy and line intensity mapping surveys.\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/99887141178 \nMeeting ID: 998 8714 1178\nOne tap mobile\n+16699006833\,\,99887141178# US (San Jose)\n+12532158782\,\,99887141178# US (Tacoma) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 998 8714 1178\nFind your local number: https://lbnl.zoom.us/u/aeqjQRsmD \nJoin by SIP\n99887141178@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 998 8714 1178 \n──────────

SUMMARY:Etienne Dreyer (Simon Fraser University) Searching for new physics using high-energy lepton pairs and some other hot topics in ATLAS
DESCRIPTION:Abstract:\nWhat is the nature of dark matter? What leads to the fundamental forces having such disparate strengths? Can we explain the small mass of the Higgs boson without excessive fine tuning? These outstanding questions are part of a broad motivation to continue investigating new physics scenarios beyond the Standard Model (SM). Several theoretical solutions propose an extended gauge symmetry group beyond the SM\, and hence predict the existence of additional massive gauge bosons. I will discuss the latest search for a new neutral boson producing the particularly clean signature of two high energy leptons in the ATLAS detector. \nIn the second part of the talk I will share my ambitions for ongoing and future research in machine learning applications to particle physics\, testing the SM in strategic connections to the Higgs boson\, and work on the ATLAS Inner Tracker (ITk) upgrade. \nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/93348407663 \nMeeting ID: 933 4840 7663\nOne tap mobile\n+16699006833\,\,93348407663# US (San Jose)\n+13462487799\,\,93348407663# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\nMeeting ID: 933 4840 7663\nFind your local number: https://lbnl.zoom.us/u/ac8IBQ41t0 \nJoin by SIP\n93348407663@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 933 4840 7663 \n──────────

SUMMARY:Nandita Khetan (Gran Sasso Science Institute) "Cosmology in the multi-messenger era"
DESCRIPTION:Abstract: \nThe talk will present my PhD project research which focuses on advancing the standardization of various transients to be used as cosmological probes and the evaluation of the Hubble constant (H0). With SN Ia\, I will present interesting results coming from a recent work where I used an alternate way to calibrate SN Ia based on the surface brightness fluctuations (SBF) method. Besides SNe Ia\, I explored other exotic/new transients like Superluminous supernovae\, Kilonovae and Gravitational waves as distance indicators. In particular\, I worked on SLSNe in rest frame UV wavelengths to find peak luminosity correlations with light curve properties. I participated in a project exploring KNe as a standard candle to perform independent measurements of H0. I am currently working on the prospects of calibrating SNe Ia with GW distances measured from future GW detectors. I will briefly present these cosmological probes and discuss their future perspectives.\n\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94818263036 \nMeeting ID: 948 1826 3036\nOne tap mobile\n+16699006833\,\,94818263036# US (San Jose)\n+12532158782\,\,94818263036# US (Tacoma) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\nMeeting ID: 948 1826 3036\nFind your local number: https://lbnl.zoom.us/u/a9sKBohim \nJoin by SIP\n94818263036@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 948 1826 3036 \n──────────

SUMMARY:Special RPM-Berkeley Cosmology Seminar | Sihan Yuan (Harvard University) Tackling the challenges of galaxy-dark matter connection modeling and secondary bias
DESCRIPTION:Abstract: \nModeling galaxy-dark matter connection is essential in deriving unbiased cosmological constraints from galaxy clustering observations. We show that a more physically motivated galaxy-dark matter incorporating secondary biases can result in more accurate predictions of galaxy clustering\, and that it significantly reduces the tension in galaxy lensing. We further present progress in building a galaxy-dark matter connection framework that is rich in features and highly efficient in evaluation\, enabling more robust cosmological analyses with upcoming DESI data.\n \n\n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/97518801157 \nMeeting ID: 975 1880 1157\nOne tap mobile\n+16699006833\,\,97518801157# US (San Jose)\n+13462487799\,\,97518801157# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 975 1880 1157\nFind your local number: https://lbnl.zoom.us/u/adtjQZqJZT \nJoin by SIP\n97518801157@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 975 1880 1157 \n──────────

SUMMARY:Kevin Woods (Stony Brook University) "Measuring neutrino oscillations with accelerator-based\, long-baseline experiments"
DESCRIPTION:Abstract: \n\nAccelerator-based\, long-baseline neutrino oscillation experiments are uniquely positioned to explore the CP-violating nature of the neutrino sector. This talk will briey discuss the experimental technique before surveying selected topics spanning both current and future generations of such experiments. First\, the Bayesian Markov Chain Monte Carlo oscillation analysis of the T2K experiment\, which has been accumulating data for the past 10 years\, will be presented before discussing the ongoing efforts to extend the analysis framework to be used in a joint analysis between T2K and the NOA experiment at Fermilab. The experience obtained from these experiments already in the data taking stages has been and will continue to be invaluable in the design of future experiments\, such as the Deep Underground Neutrino Experiment (DUNE). The DUNE collaboration will employ the liquid argon time projection chamber (LArTPC) technology at an unprecedented scale to measure neutrino interactions at its far site. The talk will conclude with an overview of the realization and operation of the protoDUNE-SP detector\, a prototype for a DUNE far detector module\, for a charged particle test beam run that took place at CERN in the end of 2018 \n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/97143316113 \nMeeting ID: 971 4331 6113\nOne tap mobile\n+16699006833\,\,97143316113# US (San Jose)\n+13462487799\,\,97143316113# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 971 4331 6113\nFind your local number: https://lbnl.zoom.us/u/ad5JPUF20z \nJoin by SIP\n97143316113@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 971 4331 6113 \n──────────

SUMMARY:Kathryn Sutton (Columbia University Department of Physics) "MicroBooNE's Search for a Photon-Like Low Energy Excess"
DESCRIPTION:Abstract: \n\nMicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) detector and is the first of three such detectors to be commissioned as part of the Short Baseline Neutrino (SBN) program at Fermilab (FNAL)\, and has been taking data since 2015. One of its primary goals is to investigate the unexplained excess of electromagnetic events in the lowest energy ranges observed in the same neutrino beamline at the MiniBooNE experiment. While one leading interpretation of this anomaly is electron neutrino appearance due to sterile neutrino oscillations\, a viable Standard Model explanation is neutrino-induced single photon events. The MicroBooNE single photon analysis looks to test this interpretation by measuring the rate of neutrino-induced resonant neutral current (NC) delta baryon production and subsequent delta radiative decay with a single photon in the final state\, NC Δ→N𝛾. This measurement of a process that has never been observed before is projected to improve upon the current experimental limit from T2K by greater than a factor of thirty. This talk will present the status of the MicroBooNE single photon search\, as well as ongoing work to create a more complete picture of single photon production in the SBN program.\n\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98026016121 \nMeeting ID: 980 2601 6121\nOne tap mobile\n+16699006833\,\,98026016121# US (San Jose)\n+13462487799\,\,98026016121# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 980 2601 6121\nFind your local number: https://lbnl.zoom.us/u/abAl5nOK8c \nJoin by SIP\n98026016121@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 980 2601 6121 \n──────────
