SUMMARY:Ken Bloom (UNL) "Climate Impacts of Particle Physics: A Sustainability Agenda"
DESCRIPTION:ABSTRACT: (This is a Hybrid/ZOOM Meeting)\nThe pursuit of particle physics requires a stable and prosperous society.  Today\, our society is increasingly threatened by global climate change.  Human-influenced climate change has already impacted weather patterns\, and global warming will only increase unless deep reductions in emissions of CO2 and other greenhouse gases are achieved.  Current and future activities in particle physics need to be considered in this context\, either on the moral ground that we have a responsibility to leave a habitable planet to future generations or on the more practical ground that\, because of their scale\, particle physics projects and activities will be under scrutiny for their impact on the climate.  I will discuss a white paper for the Snowmass workshop that I co-authored\, in which we considered several contexts in which the practice of particle physics has impacts on the climate.\n \n──────────\n\n \nTroy Cortez is inviting you to a scheduled Hybrid/Zoom Meeting. \nConference Room Location: 50-5132 at 4:00 PM – TODAY \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94367647939?pwd=UEJQRjhlaGc4dFFqT1c1WEtRSnVRZz09 \nMeeting ID: 943 6764 7939\nPasscode: 531399\nOne tap mobile\n+16699006833\,\,94367647939#\,\,\,\,*531399# US (San Jose)\n+12133388477\,\,94367647939#\,\,\,\,*531399# US (Los Angeles) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\n+1 646 518 9805 US (New York)\n+1 646 558 8656 US (New York)\n+1 651 372 8299 US (Minnesota)\n+1 786 635 1003 US (Miami)\n+1 267 831 0333 US (Philadelphia)\n+1 301 715 8592 US (Washington DC)\n+1 312 626 6799 US (Chicago)\n+1 470 250 9358 US (Atlanta)\n+1 470 381 2552 US (Atlanta)\nMeeting ID: 943 6764 7939\nPasscode: 531399\nFind your local number: https://lbnl.zoom.us/u/adUylfsSvF \nJoin by SIP\n94367647939@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 Sydney)\n103.122.167.55 (Australia Melbourne)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 943 6764 7939\nPasscode: 531399 \n──────────

SUMMARY:HYBRID TALK | David Weinberg (Ohio State U./Visiting UCB Miller Professor) "Decoding the Origin of the Elements"
DESCRIPTION:Abstract: \n\nThe elemental abundance patterns of stars encode a wealth of information about the history of the Milky Way galaxy and the astrophysical processesthat create atomic nuclei.  I will describe some of what we have learned about the origin of elements in the Milky Way from the SDSS APOGEE survey\, which has measured detailed abundance patterns (typically 15-18 elements\nper star) for half a million stars.  The average chemical enrichment and the relative contributions from core collapse (massive star) supernovae and Type Ia (white dwarf) supernovae changes systematically with position in the Galaxy.  However\, the observed median trends of element abundance ratios are nearly independent of position\, and the abundance pattern of\na typical APOGEE star can be described with two free parameters and residuals at the few-percent level.  By isolating the enrichment pattern of core collapse supernovae we can test theoretical models of massive star evolution and black hole formation.  Other elements such as nitrogen and cerium provide clues to the mixing of nuclear-processed material within intermediate mass stars.  The most important degeneracy in Galactic chemical evolution models is the tradeoff between the overall yield of heavy elements (sensitive to black hole formation) and the ejection of elements in galactic winds. Measurement of deuterium and helium-3 can help break this degeneracy because these isotopes originate primarily or entirely in the big bang.\n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94367647939?pwd=UEJQRjhlaGc4dFFqT1c1WEtRSnVRZz09 \nMeeting ID: 943 6764 7939\nPasscode: 531399\nOne tap mobile\n+16699006833\,\,94367647939#\,\,\,\,*531399# US (San Jose)\n+12133388477\,\,94367647939#\,\,\,\,*531399# US (Los Angeles) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\n+1 646 518 9805 US (New York)\n+1 646 558 8656 US (New York)\n+1 651 372 8299 US (Minnesota)\n+1 786 635 1003 US (Miami)\n+1 267 831 0333 US (Philadelphia)\n+1 301 715 8592 US (Washington DC)\n+1 312 626 6799 US (Chicago)\n+1 470 250 9358 US (Atlanta)\n+1 470 381 2552 US (Atlanta)\nMeeting ID: 943 6764 7939\nPasscode: 531399\nFind your local number: https://lbnl.zoom.us/u/adUylfsSvF \nJoin by SIP\n94367647939@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 Sydney)\n103.122.167.55 (Australia Melbourne)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 943 6764 7939\nPasscode: 531399 \n──────────

SUMMARY:Anne Green (University of Nottingham) "Primordial Black Holes as a Dark Matter Candidate"
DESCRIPTION:ABSTRACT: \nDiverse astrophysical and cosmological observations indicate that most of the matter in the Universe is cold\, dark and non-baryonic. Traditionally the most popular dark matter candidates have been new elementary particles\, such as WIMPs and axions. However Primordial Black Holes (PBHs)\, black holes formed from over densities in the early Universe\, are another possibility. The discovery of gravitational waves from mergers of ~10 Solar mass black hole binaries by LIGO-Virgo has generated a surge in interest in PBH dark matter. I will overview the formation of PBHs\, the observational limits on their abundance and the key open questions in the field. \nhttp://physics.lbl.gov/rpm/index.php/events/

SUMMARY:Matt Kramer (LBNL) - "Measurement of sin²2θ₁₃ and Δm²ₑₑ from the Full Dataset of the Daya Bay Experiment"
DESCRIPTION:ABSTRACT: (This is a Hybrid/ZOOM Meeting)\nThe Daya Bay Reactor Neutrino Experiment was built to measure the smallest neutrino mixing angle\, θ₁₃\, using the oscillation of electron antineutrinos produced by the Daya Bay nuclear power complex in southern China. Using the rate and spectral shape of antineutrino events at multiple baselines from the reactors\, sin²2θ₁₃ is extracted along with the effective mass splitting Δm²ₑₑ. This talk describes\, step-by-step\, the latest oscillation analysis from our full dataset of ~5.5 million antineutrinos acquired over nearly a decade. In addition to the increase in statistics\, this analysis benefits from improvements in energy reconstruction and background subtraction. With an uncertainty of 2.8%\, this measurement of sin²2θ₁₃ is likely to remain the world’s most precise for the foreseeable future. \n\nZOOM Talk: https://lbnl.zoom.us/j/91782268585 \nTime: 4:00 PM \n\nHybrid Location: Conference Room Location: 50-5132

SUMMARY:Hybrid Talk | Aaron Manalaysay (LBNL) "First results from the LZ dark matter search"
DESCRIPTION:Abstract:\nThe question of what the identity of dark matter is\, presents one of the most fundamental mysteries in physics today. An answer to this question will shed light on a wealth of physics beyond the Standard Model\, and will have a fundamental impact on our understanding of the universe from the smallest to the largest scales. A global experimental effort has been ongoing for almost forty years to directly detect dark matter in the laboratory\, and devices utilizing liquid xenon (LXe) have emerged as the leading technology in this search. LUX-ZEPLIN is the largest and most sensitive LXe dark-matter experiment to ever be constructed\, and has been many years in the making. Completing the final construction and commissioning tasks in the depths of the COVID lockdown\, LZ has finally turned on and collected its first science data. An exciting glimpse of what is yet to come\, I will present these first data and what they tell us about dark matter so far. \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/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:Samir Gambhir and Stephen Menendian\, UCB - The Inclusiveness Index
DESCRIPTION:The Physics IDEA Committee has invited Samir Gambhir\, Director of the Equity Metrics Program\, and Stephen Menendian\, Assistant Director\, members of the Othering & Belonging Institute\, University of California\, Berkeley\, will present their findings on the Inclusiveness Index. They have ranked every US state (and 133 countries) by their levels of inclusion. \nThe Inclusiveness Index examines inclusivity in terms of race\, religion\, gender (sex)\, sexual orientation\, and disability\, among other social groups using several measures. These include outgroup violence; political representation; income inequality; anti-discrimination laws; rates of incarceration; and immigration/asylum policies. \nThis will be an LBNL Hybrid Event: \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585 \nConference Room: 50A-5132

SUMMARY:David Dunsky (LBNL) "Dark Radiation Constraints on Heavy QCD Axion Theories"
DESCRIPTION:Abstract: The explicit breaking of the PQ symmetry by higher dimensional operators can spoil the dynamical relaxation of the strong CP angle to its minimum of zero. One solution to this PQ “quality problem” is to introduce heavy QCD axions. Such axions acquire a mass from physics occurring far above the QCD scale and possess a potential more robust to corrections from higher dimensional PQ breaking operators. However\, in much of the (m_a\, f_a) plane\, heavy QCD axions can generate large amounts of dark radiation when decaying. In this talk\, I will discuss the cosmological evolution of heavy QCD axions in the early Universe\, their interactions with the Standard Model thermal bath\, and precise dark radiation constraints arising from their decays. In addition\, I will discuss how including a mirror photon – common in heavy axion theories involving mirror QCD sectors – modifies this picture and can lead to dangerous amounts of dark radiation

SUMMARY:Bibhushan Shakya (DESY) - "Gravitational Wave Probes of the Dark Universe"
DESCRIPTION:ABSTRACT: (This is a Hybrid/ZOOM Meeting)\n \n\n\n\nGravitational waves offer a powerful probe of early Universe phenomena. A particularly well-motivated BSM target for gravitational wave experiments is a first order phase transition in a dark sector\, where bubbles of true vacuum nucleate and expand in a background of false vacuum. We will discuss several new ideas related to gravitational wave signals from such dark phase transitions\, including novel forms of gravitational wave signals beyond the traditionally studied ones sourced by bubble collisions and sound waves\, as well as prospects of detecting phase transitions that could have been responsible for the production of dark matter through various nonthermal mechanisms. \n\nJoin Zoom Meeting: \nhttps://lbnl.zoom.us/j/94367647939?pwd=EJQRjhlaGc4dFFqT1c1WEtRSnVRZz09 \nMeeting ID: 943 6764 7939\nPasscode: 531399\n\n\nTime:         4:00 PM\n\nConference Room Location: 50-5132\n\n      Bibhushan Shakya (DESY) Webpage: https://sites.google.com/view/bibhushan-shakya

SUMMARY: James Unwin (UIC) "The Prospect of Nearby Primordial Black Holes"  
DESCRIPTION:Abstract:\nPrimordial Black Holes are a potential candidate for explaining some\, or even all\, of the experimentally inferred dark matter abundance. In this talk I will motivate the existence of Primordial Black Holes and discuss their potential role as a dark matter candidate. Notably\, for light Primordial Black Holes there could be a large abundance of such objects in the vicinity of the solar system potentially leading to distinct astrophysical signals. Moreover\, I will highlight that one can explain gravitational anomalies observed in small bodies with orbits beyond Neptune\, which have been taken to be indicative of a large ninth planet in the outer Solar System\, can be explained by a planetary mass Primordial Black Hole which has been gravitationally captured by the Sun.\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/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:HYBRID TALK | Mengjiao Xiao (MIT) "In Search of Cosmic-Ray Antinuclei from Dark Matter with the GAPS Experiment"
DESCRIPTION:Abstract:\nThe origin of dark matter is a driving question of modern physics. Finding dark matter in the laboratory and elucidating its properties could revolutionize our understanding of the fundamental building blocks of the universe. The common challenges for dark matter searches in astrophysical signatures are large and uncertain backgrounds. The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment designed to identify low-energy cosmic antinuclei\, in particular antideuterons from dark matter annihilation or decay\, using the uniquely characterized atomic X-rays and charged particles from the decay of exotic atoms. With such a novel detection approach\, benefitting from a custom- d eveloped large- area silicon tracker and a large-acceptance Time-of-Flight system\, GAPS is sensitive to antideuterons and even antiheliums with the kinetic energy ≤0.25 GeV/n\, which should offer an essentially background-free region to probe many generic dark matter models. Additionally\, GAPS will collect a high-statistics antiproton spectrum in an unexplored energy range\, and open a sensitivity to cosmic antihelium. \nThe GAPS instrument consists of a tracker of >1000 custom Si(Li) detectors; a precision- timing\, large-area time-of-flight system; and a novel oscillating heat pipe thermal system. GAPS is currently under integration and preparing for the first Antarctic balloon flight in late 2023 while two follow-up flights are planned. This talk will present the science impact of the GAPS experiment\, while focusing on its custom-developed instrument technology\, including the design principle\, commissioning of the GAPS functional prototype\, integration and testing of GAPS full payload\, and the path forward to the initial flight. \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:HYBRID TALK| Hee-Jong Seo "Accelerating Universe through DESI"
DESCRIPTION:Abstract \nOne of the most intriguing questions in physics today is the nature of dark energy that is responsible for the accelerated expansion of the Universe. Three-dimensional maps of galaxies from spectroscopic galaxy surveys provide a giant laboratory to test the nature of the Universe\, including dark energy\, in a way that is complementary to other cosmic surveys. DESI\, being the largest galaxy redshift survey up to date\, is currently preparing for the first-year cosmology analysis release in Summer 2023\, In this talk\, among the key science goals of DESI\,  I want to focus on the studies of two accelerated expansion phases of the Universe using DESI\, one today due to dark energy and the other\, cosmic inflation right after the Big Bang. For the former\, I will show the first Baryon Acoustic Oscillation detection result using only the first two months of the DESI data. For the latter\, I will discuss how we can fight the observational systematics using neural networks and derive a tight constraint on inflation using the DESI Legacy survey.

SUMMARY:SPEAKER - Edward Callaghan - (UCB) - Optical Neutrino Detectors of the Past\, Present\, and Future
DESCRIPTION:TITLE: Optical Neutrino Detectors of the Past\, Present\, and Future \nABSTRACT: Large-volume optical detectors are a mainstay of experimental\nneutrino physics\, with several successful implementations in the past\ndecades and larger models on the horizon. Traditionally\, such detectors\nmake use of either Cherenkov radiation\, produced as a superluminal\ncharged particle stops\, or scintillation light\, produced from the\ndeexcitation of excited molecular states\, but rarely both in tandem. I\nwill describe an R&D campaign to develop technologies suitable for a\nhybrid detector\, which will exploit both Cherenkov and scintillation\nlight to implement advanced event reconstruction techniques. This\ncampaign has culminated in the Eos demonstrator project\, which will be\nlocated on the UC Berkeley campus and act as a ton-scale demonstration\nof technologies applicable for Theia\, a proposed 25+ kiloton hybrid\ndetector. I will further discuss my work measuring cosmogenic background\nproduction in SNO\, a heavy water Cherenkov detector\, and a search for\nextraterrestrial antineutrinos in SNO+\, an upgrade to SNO\, which has\ncompleted a phase of water running and is now filled with liquid\nscintillator. \nThis is a HYBRID Meeting \n\nLocation:    50A-5132\nTime:        4:00 – 5:00 PM\nTitle:       “Snowmass Report Highlights – Part 3”\n\nZOOM Information: \nJoin Zoom Meeting \n50A-5132 (Sessler Conference Room)\, https://lbnl.zoom.us/j/91782268585

SUMMARY:SPEAKER - Andrzej Novak - RWTH Aachen University - Title: Searches for Higgs to Charm Decays with the CMS Experiment using Novel ML Methods
DESCRIPTION:TITLE: Searches for Higgs to Charm Decays with the CMS Experiment using Novel ML Methods \n\nABSTRACT: Searches for charm decays of the Higgs boson are not only limited by the small coupling but primarily by the considerable difficulty of identifying charm jets. However\, recent advances in machine learning methods have drastically improved the performance of flavour identification algorithms. Applying them in analyses of the LHC Run2 data has enabled us to improve the limit on the Higgs to charm rate by a factor of 20 in the last few years. I will give an overview of the latest results obtained with the CMS experiment\, focusing on the more recent boosted search. \n\nZOOM Information –  \n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\n

SUMMARY:SPEAKER: Daniel Kodroff (Penn State) - TITLE: Background Modeling and First Results From The LUX-ZEPLIN Dark Matter Experiment
DESCRIPTION:This is a VIRTUAL Event \nTITLE: Background Modeling and First Results From The LUX-ZEPLIN Dark Matter Experiment \nABSTRACT: LUX-ZEPLIN (LZ) is a dark matter experiment located at the Sanford Underground Research Facility in South Dakota\, USA employing a 7 tonne active volume of liquid xenon in a dual-phase time projection chamber (TPC). It’s surrounded by an instrumented xenon “skin” region and gadolinium-loaded liquid scintillator outer detector\, primarily serving as active vetoes for gamma-ray and neutron backgrounds\, respectively\, all contained within an ultra-pure water tank. A comprehensive material\nassay and selection campaign for detector components\, along with a xenon purification campaign\, have further ensured an ultra-low background environment. These mitigations have allowed LZ to achieve a background rate of (63.0 ± 4.5) x 10−6 events/keVee/kg/day in the low energy region\, approximately 60 times lower than that of its predecessor LUX experiment. In this low background region\, LZ has recently set new world-leading limits for the spin-independent elastic scattering of nuclear recoils of Weakly Interacting Massive Particles (WIMPs) with masses above 9 GeV/c^2 using an exposure of 60 live days and a fiducial mass of 5.5 tonnes. This talk will provide an overview of the LZ detector and a description of its backgrounds with an emphasis on techniques to constrain these backgrounds in situ. I will also discuss the first results from LZ and briefly discuss its future science program. \nZOOM Information – \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Chen-Hsun (Jay) Chan - University of Wisconsin\, Madison - TITLE: Search for Higgs Boson Decaying to Dimuon
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Search for Higgs Boson Decaying to Dimuon \nABSTRACT: \nThe search for Higgs boson decaying to dimuon is currently the most promising channel to probe the Yukawa coupling to the second-generation fermions. In this seminar\, I will give an overview of the recent search for Higgs boson decaying to dimuon\, using the proton-proton collision data collected by the ATLAS detector between 2015 and 2018. Despite excellent muon reconstruction\, this search is particularly challenging due to the small Higgs to dimuon decay branching ratio and the large amount of Standard Model background. Multiple techniques are developed in order to overcome the challenges and significantly enhance the sensitivity compared to the previous iteration.\n\nWith more data to be collected in the near future\, it is possible to observe the Higgs to dimuon signal at 5 standard deviation. I will highlight several expected improvements during LHC run-3\, which will benefit this measurement. Furthermore\, the upgrade to High-Luminosity LHC (HL-LHC) will bring a significant improvement to this measurement\, thanks to the increased data statistics as well as the upgrade of the ATLAS Inner Tracker (ITk). I will\, in the end\, discuss the recent development of the ITk pixel upgrade\, particularly the testing of the pixel module serial powering.\n\n\nZOOM Information – \n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Kate Storey-Fisher - New York University - TITLE: Galaxy Clustering with Emulation and Equivariant Machine Learning
DESCRIPTION:This is a Virtual Event \nLocation: Zoom from campus In Campbell Hall\, Room 131\n \nTITLE: Galaxy Clustering with Emulation and Equivariant Machine Learning \nABSTRACT: \n\nThere is significant untapped cosmological information in the clustering of galaxies\, particularly at small scales. I will discuss two projects aimed at this. In the Aemulus project we take an emulation approach\, populating dark matter only cosmological simulations with a simple galaxy–halo connection model and training machine learning (ML) emulators to predict clustering statistics. I will show that incorporating beyond-standard statistics sensitive to the local environment aids in constraining galaxy bias parameters and increases the precision on recovered cosmological parameters. \nTo account for uncertainties in galaxy formation\, we require improved models of the galaxy–halo connection. I will present a new equivariant ML approach to learning the relationship between dark matter halo and galaxy properties in cosmological simulations. Our approach explicitly respects physical symmetries by describing halos in terms of a large set of invariant dimensionless scalars. I will show that this results in precise predictions of galaxy properties. These frameworks will be critical for the analysis of upcoming spectroscopic surveys. \n\n\nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585

SUMMARY:SPEAKER: Chamindu (Chami) Amarasinghe – U. of Michigan – TITLE: Expansive Dark Matter Searches with LZ
DESCRIPTION:This is a VIRTUAL Event \nTITLE: Expansive Dark Matter Searches with LZ \n\nABSTRACT: LUX-ZEPLIN (LZ) is an underground direct detection experiment that conducted its first search for Weakly Interacting Massive Particles (WIMPs) and set world-leading upper limits on spin-independent and spin-dependent WIMP-nucleon couplings. In this talk I describe this result\, and discuss how the WIMP search can be extended by considering all possible WIMP-nucleon interactions at the energy scale of direct detection using an effective field theory (EFT) approach. I also describe how tools from machine learning are applied in the EFT search\, and how unsupervised learning can be used to detect anomalies of various sources in data. Finally\, I will briefly discuss an experimental concept to measure electron and photon yields of nuclear recoils in liquid xenon at extremely low energies (below 0.3 keVNR)\, in order to improve the sensitivity of experiments like LZ to low mass WIMPs. \nZOOM Information –\n \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585

SUMMARY:SPEAKER: Roger Huang – LBNL – TITLE: Neutrinos from Different Angles
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Neutrinos from Different Angles \nABSTRACT: \nThere still remain many outstanding questions about the behavior and properties of neutrinos\, which are the subject of a wide range of experimental programs around the world. CUORE (Cryogenic Underground Observatory for Rare Events) is a cryogenic calorimetric experiment operating at ~10 mK to search for neutrinoless double-beta (0νββ) decay in Te-130\, which could shed light on the nature of neutrino masses and whether they are Majorana particles. I will present the most recent 0νββ results from CUORE\, as well as discuss development of deep-cryogenic electronics aimed towards its next-generation upgrade to CUPID (CUORE Upgrade with Particle ID). \nIn a different regime of neutrino physics\, DUNE (Deep Underground Neutrino Experiment) is a long-baseline neutrino oscillation experiment that will enable a variety of precision measurements\, including determination of the neutrino mass hierarchy and high-resolution probes of the neutrino CP-violating phase factor. I will discuss the current status and plans for DUNE and its upcoming prototype program ProtoDUNE-II\, with a focus on the cryogenic charge readout electronics for the far detectors. I will also discuss efforts to improve neutrino cross-section unfolding methods with the aid of neural networks using the Omnifold technique \n  \n\n\nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585Meeting ID: 917 8226 8585

SUMMARY:SPEAKER: Anne Fortman – Harvard – TITLE: Searching for massive new particles using ionization energy loss and time of flight at ATLAS
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Searching for massive new particles using ionization energy loss and time of flight at ATLAS \nABSTRACT: \nDuring Run 2\, the LHC achieved collisions with a center-of-mass energy of 13 TeV\, potentially allowing us to produce new fundamental particles of higher masses than ever before. Using ionization energy loss and time-of-flight\, we can reconstruct the mass of heavy new particles predicted in a variety of models. In this talk\, we discuss the excess seen in the first-wave effort of a search using the Run 2 dataset at ATLAS\, and introduce an expanded search including time-of-flight. We present future prospects and discuss the hardware upgrades necessary to continue searching for new physics at the High Luminosity LHC. \n\nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Maria Martinez-Casales – Iowa State University – TITLE: Constraining neutrino interaction incertainties for oscillation measurements in NOvA
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Constraining neutrino interaction incertainties for oscillation measurements in NOvA \nABSTRACT: \nThe NuMI Off-Axis Neutrino Appearance (NOvA) experiment is an 810 km baseline neutrino oscillation experiment measuring the fundamental properties of neutrinos and antineutrinos\, using the high statistics data from the Near Detector (ND) at Fermilab to produce predictions for the Far Detector (FD) in Minnesota. The expected neutrino spectrum is simulated using GENIE\, with the neutrino cross section model adjusted to better describe the ND data by modifying the rate of Meson Exchange Current (MEC) interactions and the Final State Interactions. In measurements published so far\, NOvA has compared the Far Detector data to an energy spectrum obtained from a data-driven prediction method based Near Detector (ND) data called extrapolation. This talk presents an alternate approach that directly constrains physics model parameters in the NOvA simulation using the ND data. The neutrino and antineutrino simulation is divided into subsets based on the multiplicity and topology of visible particles. These samples have meaningful features that are used to constrain the neutrino interaction model and flux parameters using Poisson maximum likelihood fitting procedure. This work shows the fitting method effectively constrains the model uncertainties with pseudodata generated by randomly varying physics parameters in the ND simulation. This is an initial step towards achieving a full analysis that includes the physics model parameters constraint from the ND data fit to measure the neutrino oscillation parameters. \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Ciaran Hasnip – University of Oxford – TITLE: The DUNE Neutrino PRISM
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: The DUNE Neutrino PRISM \nABSTRACT: \nThe observation of neutrino flavour oscillations\, and the non-zero neutrino mass\, is the first confirmed measurement of physics beyond the standard model of particle physics. The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino experiment designed to study these flavour oscillations in a 1300 km baseline neutrino beam. DUNE aims to measure CP violation in the lepton sector\, determine the neutrino mass hierarchy and precisely measure the neutrino oscillation parameters in a single experiment. The Precision Reaction Independent Spectrum Measurement (PRISM) concept presents a novel way to perform a neutrino oscillation analysis\, which has the potential to significantly reduce the impact of neutrino cross section systematic uncertainties in DUNE through the use of data-driven predictions of the measured neutrino event rate. After introducing the physics of neutrino oscillations\, this seminar will review the DUNE experiment and the role PRISM will play in its physics program.  \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Jaafar Chakrani – Laboratoire Leprince-Ringuet\, CNRS\, Ecole polytechnique – TITLE: Neutrino interactions: a challenge for T2K and beyond
DESCRIPTION:This is an IN-PERSON Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Neutrino interactions: a challenge for T2K and beyond \nABSTRACT: \nNeutrino oscillations offer a unique opportunity to explore physics beyond the Standard Model. Multiple current and planned experiments aim at precisely characterizing these oscillations with neutrinos artificially produced in accelerators. This is the case of the T2K experiment\, located in Japan\, which provides one of the world-leading constraints on how neutrinos oscillate.\nAn important obstacle in the making of such results is the modeling of neutrino interactions which could bias oscillation measurements. Indeed\, the uncertainties associated with neutrino-nucleus interactions are difficult to quantify and constrain as they cover a large range of poorly-understood nuclear physics of how neutrinos interact. \nIn this seminar\, I will present how accelerator-based neutrino experiments measure these oscillations\, with a focus on how we tackle the challenge of modeling neutrino-nucleus interactions in the T2K experiment. Furthermore\, I will show how the ongoing upgrade of the T2K near detector will provide valuable information to significantly improve our understanding of neutrino interactions. Finally\, I will discuss the prospects of overcoming this challenge in the context of the next-generation experiment DUNE. \n  \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Josephine Paton – University of Oxford – TITLE: Directional Neutrino Measurements in Liquid Scintillators
DESCRIPTION:This is a VIRTUAL Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Directional Neutrino Measurements in Liquid Scintillators \nABSTRACT: \nNeutrinos are one of the most enigmatic particles in the Standard Model. Precise measurements of their properties are vital for our understanding of the subatomic world\, and may bring us closer to answering questions such as “Why do neutrinos have mass?” and “Why is the universe matter dominated?”. In order to do this\, novel technologies and methodologies are being developed to extract as much information as possible from the interactions of neutrinos on matter. \nLiquid scintillators have been utilised in neutrino detectors for decades\, benefitting from a high light yield which leads to precise energy reconstruction. However\, scintillation light is isotropic\, meaning scintillator detectors do not benefit from the directional information used in Cherenkov-based neutrino detectors. Significant investment has been put into developing new methods to extract Cherenkov information from scintillation signals\, allowing for a combination of energy precision and directional background rejection. In this talk I outline the methods developed for directional reconstruction in the SNO+ experiment\, and present the first demonstration event-by-event directionality of solar neutrinos in a high yield scintillator. \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

DESCRIPTION:This is an in-person Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Excitement and Challenges with Multiplexed Spectroscopic Galaxy Surveys \nABSTRACT: \nThe ongoing Dark Energy Spectroscopic Instrument (DESI) Survey is collecting galaxy redshifts at an astounding rate. Analysis from this new data promises exciting new constraints on big cosmological problems such as dark energy models and primordial non-gaussianity along with a measurement of the sum of the neutrino masses. Key technologies including the robotic focal plane system help enable nearly 5\,000 simultaneous spectra with on average 2 minutes between exposures. In this talk I will describe some of the challenges encountered optimizing the DESI instrument for science results. Furthermore\, I will discuss some of the impact the focal plane and fiber assignment algorithms have on galaxy clustering data and some novel mitigations I am exploring to resolve this problem. Finally\, I will conclude with a look to the future and how we can engage in current efforts to build on the success of DESI. \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585
