SUMMARY:Vivek Singh (LBNL) "New results for Neutrinoless Double-Beta Decay search in 130Te with CUORE "
DESCRIPTION:Abstract:  \nThe CUORE experiment — with a detector array comprising 988 cube-shaped radiopure natTeO2 crystals — is the world’s largest and most sensitive low temperature calorimetric search for neutrinoless double beta (0νββ) in 130Te. We completed the construction of the experiment in August 2016 and started science data taking in Spring 2017. Since our first results from Fall 2017\, we have quadrupled our exposure and have bettered the sensitivity for the $0\nu\beta\beta$ search using analysis improvements. In this talk\, I will delve into the data taking campaign\, analysis techniques\, and discuss the recent physics results from the full CUORE datasets accumulated over the last two years.

SUMMARY:Huilin Qu (UCSB) "Search for the Higgs Boson Decaying to Charm Quarks with the CMS Experiment"
DESCRIPTION:Abstract: \n\n \nAfter the discovery of the Higgs boson at the LHC\, thoroughly studying the properties of the Higgs boson has become one of the top priorities of the LHC physics program. Measurement of the decay of the Higgs boson to charm quarks provides a direct probe of the Higgs coupling to second-generation quarks\, therefore it is crucial for understanding the structure of Yukawa couplings. However\, such a measurement is extremely challenging at the LHC due to large backgrounds. Recently\, a search for the Higgs boson decaying to charm quarks has been performed in the CMS experiment. Novel approaches and advanced machine learning-based techniques for the Higgs boson reconstruction and charm quark identification are adopted in this analysis\, leading to significantly improved results compared to previous experimental searches.\n\n

SUMMARY:Matthew Solt (Stanford U) "The Heavy Photon Search Experiment
DESCRIPTION:Abstract: \n  \nThe Heavy Photon Search (HPS) experiment is a fixed target experiment at Jefferson Lab searching for a new dark-force mediator called a heavy photon (or dark photon or A’). A heavy photon is a hypothetical U(1) vector boson that couples to the Standard Model photon through kinetic mixing\, and thus can be produced in a process analogous to bremsstrahlung by an electron beam incident on a dense target. If kinematically allowed\, subsequent decays into e+e- pairs can be detected by the HPS detector – a compact\, large acceptance spectrometer consisting of a silicon vertex tracker and lead-tungstate electromagnetic calorimeter. For large couplings\, heavy photons would appear as a resonance peak in the invariant mass spectrum on top of a large QED background. For sufficiently small couplings\, heavy photons are long-lived and would appear as decay vertices displaced from the target beyond a prompt QED background. In this talk\, I will discuss the motivation for heavy photons and the HPS detector. I will then focus on the displaced vertex analysis and discuss the results from our engineering in 2015 (1.06 GeV beam energy)\, the ongoing analysis of the engineering run in 2016 (2.3 GeV beam energy)\, and finally the upgrades and commissioning of our most recent physics run in 2019 (4.55 GeV beam energy).

SUMMARY:Callum Wilkinson (Albert Einstein Center for Fundamental Physics) "Precision neutrino oscillation physics and DUNE "
DESCRIPTION:Abstract:  \nNeutrino oscillations have been established as an energy and distance dependent phenomena\, beyond the Standard Model of Particle Physics. However\, a number of key questions remain\, which have implications for our understanding of the origin and development of our Universe. The Deep Underground Neutrino Experiment (DUNE)\, which is currently in the planning stage\, has the potential to answer these outstanding questions and make measurements of the other parameters with unprecedented precision. This talk gives an overview of the DUNE sensitivity to oscillation parameters\, and describes a program of research aimed at reducing systematic uncertainties\, and achieving DUNE’s physics goals.

SUMMARY:Ben Safdi (U. Michigan) "The Search for Axion Dark Matter
DESCRIPTION:Abstract: \nDark matter is the dominant source of matter in our Universe.  However\, while dark matter dictates the evolution of large-scale astrophysical systems through its gravitational effects\, the particle nature of dark matter is unknown.  In this talk I will review the current status of the search for the particle dark matter candidate called the axion\, which is both well-motivated theoretically and also relatively unexplored experimentally.  I will focus specifically on new large-scale numerical simulations of axion cosmology that lead to precise predictions for (i) the axion mass that gives the correct dark matter abundance\, and (ii) the structure of dark matter on small astrophysical scales.  I will show that axion dark matter may be harder to detect directly in the laboratory than previously thought\, given that the cosmological axions are mostly confined to compact minihalos\, but that this dark matter scenario may still be detectable using radio telescope searches for axion-induced radio lines.

SUMMARY:Heidi Schellman (Oregon State U) "Computing for the DUNE Long Baseline Neutrino Oscillation Experiment "
DESCRIPTION:ABSTRACT: \n  \nThe DUNE long baseline neutrino oscillation collaboration consists of over 180 institutions from 33 countries. The experiment will consist of 4 10kT fiducial volume liquid argon TPC’s in South Dakota and a multi-system near detector at Fermilab. The far site in the Sanford Underground Laboratory is in preparation now with commissioning of the first 10kT fiducial volume Liquid Argon TPC expected over the period 2025-2028 and a long data taking run with 4 modules expected from 2029 and beyond. \nAn active prototyping program is already in place with a short test beam run with a 700T\, 15\,360 channel prototype of single-phase readout at the neutrino platform at CERN in late 2018 and tests of a similar sized dual-phase detector scheduled for mid-2019. The 2018 test beam run was a valuable live test of our computing model. The detector produced raw data at rates of up to ~2GB/s. These data were stored at full rate on tape at CERN and Fermilab and replicated at sites in the UK and Czech Republic. In total 1.8 PB of raw data were produced and reconstructed during the six week test beam run. \nBaseline predictions for the full DUNE detector data\, starting in the mid 2020’s are 30-60 PB of raw data per year. In contrast to traditional HEP computational problems\, DUNE’s Liquid Argon TPC data consist of simple but very large (many GB) 2D data objects which share many characteristics with astrophysical images. This presents opportunities to use advances in machine learning and pattern recognition as a frontier user of High Performance Computing facilities capable of massively parallel processing.

SUMMARY:Simon Knapen (IAS) "Soft signals at the LHC"
DESCRIPTION:ABSTRACT:\nThe LHC is both a Higgs and B-factory\, and for both particles it will deliver the largest data set for many decades to come. I will discuss a few examples of ways we can leverage this to search for beyond the Standard Model physics. Some ideas can be implemented now\, while others rely on the phase II detector upgrades.

SUMMARY:Raquel Castillo Fernandez (Fermilab) "Searching for Nu Physics with High Resolution Detectors"
DESCRIPTION:Abstract: \n\nNeutrino physics aims to answer some of the most pressing questions in particle physics: why the Universe is dominated by matter\, why the neutrino mass is so small and if there are more types of neutrinos. Due to the neutrino’s weakly interacting nature and the complexity of their interactions\, this research requires very large detectors able to identify low energy particles. This challenge has pushed the development of new technologies\, such as the liquid argon time projection chamber (LArTPC) detectors\, allowing for unprecedented precision in particle reconstruction\, and to expand the scientific program searching for more rare channels are present in some theories of new physics beyond the current standard model. After briefly reviewing the basis of neutrino physics\, I will introduce the main principles of the LArTPC detectors and how they can help us addressing some of the most relevant questions in particle physics. I will also describe the scientific achievements and the potential of the LArTPC neutrino program in the U.S.\, the current short (MicroBooNE/SBN) and the future long-baseline (DUNE) neutrino experiments.

SUMMARY:Ken Van Tilburg (NYU/IAS) "The Structure of Dark Matter on Small Scales"
DESCRIPTION:ABSTRACT:\n\nHalometry—mapping out the spectrum\, location\, and kinematics of nonluminous structures inside the Galactic halo—can be realized via effects that variable weak gravitational lensing induces on the proper motions of stars and other luminous background sources. Modern astrometric surveys provide unprecedented positional precision along with a leap in the number of cataloged objects. Astrometry thus offers a new and sensitive probe of collapsed dark matter structures over a wide mass range\, from one millionth to several million solar masses. It opens up a window into the spectrum of primordial density fluctuations with very small comoving wavenumbers\, scales hitherto poorly constrained.\n\nI will outline a program of detection strategies for dark matter substructure based on time-domain weak gravitational lensing\, after summarizing existing techniques and constraints. I will present first results from analyses based on Gaia’s second data release. Finally\, I will show that minimal models of axion-like dark matter naturally produce dense small-scale structures which can probed by the aforementioned astrometric lensing techniques.

SUMMARY:David Caratelli (Fermilab) "Neutrinos at Short Baselines: the MicroBooNE Experiment"
DESCRIPTION:Abstract: \n\nWhile neutrino oscillation physics has entered an era of precision measurements\, several anomalies in experiments at short baselines remain without a satisfactory answer.\n\nThe MicroBooNE experiment has been recording neutrino interactions on Fermilab’s Booster Neutrino Beam since 2015 employing a liquid argon TPC detector. This talk will present recent progress on MicroBooNE’s measurement of electron neutrinos aimed at addressing past anomalies observed by the MiniBooNE collaboration.\n\nFinally\, I will talk about how developments in the ability to use liquid argon TPC detectors in the sub-GeV regime can open new opportunities in neutrino and rare-event physics with Fermilab’s upcoming short- and long-baseline neutrino programs.\n

SUMMARY:Richard Bonventre (LBNL) "Searching for Muon to Electron Conversion: The Mu2e Experiment at Fermilab"
DESCRIPTION:Abstract: \n \nThe Mu2e experiment will search for the charged lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus\, reaching a 90% C.L. limit of 8×10^-17 on the conversion rate. This sensitivity is a four-orders of magnitude improvement over previous experiments\, and allows Mu2e to probe new physics at mass scales up to 10^4 TeV\, far beyond the direct reach of colliders. Mu2e is currently under construction at Fermilab\, and expects to begin data taking in 2023. In this talk I will present the current status of the experiment. I will also discuss the development of Mu2e detector simulations as well as the results and impact of prototype data analyses.\n

SUMMARY:Tom Melia (Kavli IPMU - Japan)“ 'CMB-ing' the Search for New Physics at Colliders"
DESCRIPTION:Abstract:\n\nThe effect of dark matter and dark energy in the universe can be inferred through measurements of anisotropies in the cosmic microwave background (CMB). The quantum effect of new physics on collisions at the Large Hadron Collider can be similarly inferred through measurements of what could be considered “anisotropies” in standard model processes. But how precise can one make the analogy? For example\, does it make sense to talk of a “power spectrum of the standard model”? In this talk I will show how to construct just such a power spectrum\, via a solution to a long-standing problem in effective field theory\, and a hidden geometry in Fermi’s Golden Rule.

SUMMARY:Keisuke Harigaya (IAS) “ Physics beyond the standard model from Higgs Parity”
DESCRIPTION:Abstract: \n\nThe discovery of the Higgs boson has revealed that the quartic Higgs self-coupling becomes small at very high energy scales. Guided by this observation\, I introduce Higgs Parity\, which is a spontaneously broken symmetry exchanging the standard model Higgs with its parity partner. In addition to explaining the small Higgs quartic coupling\, Higgs Parity can provide a dark matter candidate\, solve the strong CP problem\, and arise from an SO(10) grand unified gauge symmetry. I will show that the Higgs Parity symmetry breaking scale is determined by standard model parameters and predicts experimental signals such as the dark matter direct detection rate and the proton decay rate. As a result\, Higgs Parity provides a tight correlation between future precision measurements of standard model parameters and these experimental signals

SUMMARY:Ka Vang Tsang (SLAC) "Imaging Neutrinos: Machine Learning in LArTPC"
DESCRIPTION:Abstract:\n\nEver since the discovery\, neutrinos have proven to be one of the most intriguing subatomic particles. In the past two decades\, we have made tremendous progress in the establishment of the neutrino oscillation phenomenon. We are now able to reveal the nature using neutrinos\, such as CP violation in the lepton sector\, the neutrino mass hierarchy\, and the possible existence of the sterile neutrinos.\nLiquid argon time projection chamber (LArTPC) is a novel technology for neutrino detection because of its excellent imaging capability of charged particles. However\, it is challenging to reconstruct and analyze LArTPC events efficiently in large scale detectors.  In this talk\, I will review some revolutionary ideas in machine learning\, and demonstrate the use of these techniques to tackle the challenge in LArTPC event reconstruction.

SUMMARY:Daniel Ruterbories (Rochester U) "Electroweak Probes of the Nucleus and the Era of Precision Neutrino Physics"
DESCRIPTION:ABSTRACT: \nNeutrino oscillation experiments such as NOvA and T2K search for the disappearance and appearance of muon and electron flavor neutrinos in a predominately muon-type beam. These experiments are currently measuring the oscillation parameters to greater precision but will not be able to measure the CP phase with enough significance to pin down CP violation in the lepton sector. The next generation of experiments\, DUNE and Hyper-Kamiokande\, will push the field into its precision era\, requiring precise predictions of the flux and neutrino interactions used to measure CP violation. \nThe MINERvA experiment is a dedicated neutrino interaction experiment set in the NuMI beamline at Fermi National Accelerator Laboratory. The purpose of the experiment is to measure neutrino interactions off a variety of nuclear targets to probe nuclear effects and inform modeling of neutrino interactions. The experiment measures interactions over a wide range of Q2 and W kinematics. These including interactions in the quasi-elastic\, resonant\, and shallow to deep inelastic scattering regions. The experiment has run with two beam energies peaked at ~3 and 6 GeV in both neutrino and anti-neutrino enhanced modes. \nIn this seminar\, I will describe the current state of neutrino-nucleus interaction physics and how MINERvA data will inform future experiments. Specifically\, I will describe the extensive tuning exercise MINERvA has done to describe interactions in the quasi-elastic into the resonant pion regions of kinematic phase space. I will also discuss lessons learned and describe some of the next generation measurements necessary to prepare for the DUNE experiment. \n  \n\n──────────\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/372309777 \nMeeting ID: 372 309 777 \nOne tap mobile\n+16699006833\,\,372309777# US (San Jose)\n+13462487799\,\,372309777# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\nMeeting ID: 372 309 777\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n372309777@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 372 309 777 \n──────────

SUMMARY:Masha Baryakhtar (NYU) " New Physics Across the Spectra"
DESCRIPTION:ABSTRACT: \nTheories beyond the Standard Model of particle physics often predict new\, light\, feebly interacting particles whose discovery requires novel search strategies. A light particle\, the QCD axion\, elegantly solves the outstanding strong-CP problem of the Standard Model; cousins of the QCD axion can also appear\, and are natural dark matter candidates. First\, I will discuss my experimental proposal based on thin films\, in which dark matter can efficiently convert to detectable single photons. A prototype experiment is underway\, and current techniques promise to reach significant new dark matter parameter space. \nSecond\, I will show how rotating black holes turn into axionic beacons. When an axion’s Compton wavelength is comparable to a black hole size\, energy and angular momentum from the black hole source exponentially-growing bound states of particles. I will discuss new results on axion interactions\, including new dynamics in the bound states\, and show how black holes populate the universe with axion waves that can be detected in future laboratory searches.

SUMMARY:Christopher Marshall (LBNL) "The Dawn of DUNE: Neutrino Oscillations in the Precision Era"
DESCRIPTION:ABSTRACT: \nNeutrino oscillation is a well-established phenomenon. Over the past two decades\, nearly all of the parameters governing these oscillations have been measured experimentally\, using neutrinos from the atmosphere\, the sun\, nuclear reactors\, and particle accelerators. The remaining unknowns have very interesting consequences but are challenging to access experimentally as they require high-precision measurements. The Deep Underground Neutrino Experiment (DUNE) will be sensitive to these unknowns\, including whether neutrinos violate CP symmetry\, which could be the key to understanding why the universe is matter-dominated. Constraining systematic uncertainties is critical for DUNE to reach its physics goals\, and requires a highly-capable near detector. I will present the discovery potential of DUNE and discuss how the experiment is designed to address the many challenges of precision neutrino oscillation physics. I will give particular focus to how the near detector can mitigate large uncertainties on the neutrino flux prediction and interaction cross sections. \n  \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/429952456 \nMeeting ID: 429 952 456 \nOne tap mobile\n+16699006833\,\,429952456# US (San Jose)\n+13462487799\,\,429952456# 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\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 429 952 456\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n429952456@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 429 952 456 \n──────────

SUMMARY:Richard Bonventre (LBNL) "Searching for Muon to Electron Conversion: The Mu2e Experiment at Fermilab"
DESCRIPTION:Abstract:\nThe Mu2e experiment will search for the charged lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus\, reaching a 90% C.L. limit of 8×10^-17 on the conversion rate. This sensitivity is a four-orders of magnitude improvement over previous experiments\, and allows Mu2e to probe new physics at mass scales up to 10^4 TeV\, far beyond the direct reach of colliders. Mu2e is currently under construction at Fermilab\, and expects to begin data taking in 2023. In this talk I will present the current status of the experiment. I will also discuss the development of Mu2e detector simulations as well as the results and impact of prototype data analyses.

SUMMARY:Adi Ashkenazi (Fermilab) "Probing V Interactions for V Physics"
DESCRIPTION:Abstract:\n\nThe ability of current and next generation accelerator based neutrino oscillation measurements to reach their desired sensitivity requires a high-level of understanding of the neutrino-nucleus interactions. These include precise estimation of the relevant cross sections and the reconstruction of the incident neutrino energy from the measured final state particles. Incomplete understanding of these interactions can skew the reconstructed neutrino spectrum and thereby bias the extraction of fundamental oscillation parameters and searches for new physics. In this talk I will present the first exclusive differential cross section measurement using neutrino-Argon Quasi Elastic like interactions from the MicroBooNE experiment. In addition\, using wide phase-space electron scattering data\, collected using the CLAS spectrometer at the Thomas Jefferson National Accelerator Facility (JLab)\, the reconstruction of the incoming lepton energy from the measured final state is being tested. Disagreements with current event generators\, used in the analysis of neutrino oscillation measurements\, are observed which indicate underestimation of nuclear effects. The impact of these findings on bias in oscillation analyses will be discussed.\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/415426450 \nMeeting ID: 415 426 450 \nOne tap mobile\n+16699006833\,\,415426450# US (San Jose)\n+13462487799\,\,415426450# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\nMeeting ID: 415 426 450\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n415426450@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 415 426 450 \n──────────

SUMMARY:Lina Necib (Caltech) "Dark Matter in the Era of Gaia"
DESCRIPTION:ABSTRACT: \nThe Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way\, making it the largest stellar catalog at hand. Simultaneously\, recent developments in cosmological simulations have made it possible to track stars and dark matter in realistic Milky Way-like galaxies. In this talk\, I will demonstrate how using cutting-edge simulations and Gaia data in tandem has enabled me to start building the first local map of the cold dark matter phase space distribution in our Galaxy. Doing so led me to discover Nyx\, a stream of stars in the solar neighborhood that I identified using machine learning methods. Nyx\, potentially the result of a prograde merger\, is crucial in understanding the formation of the disk of the Milky Way as it might have been associated with an accreted dark disk. Finally\, I will summarize how future surveys will help fully map out the phase space distribution of dark matter in the Milky Way\, and show that such an empirical map will have extensive ramifications for dark matter searches. \n\n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/629888022Meeting ID: 629 888 022 \nOne tap mobile\n+16699006833\,\,629888022# US (San Jose)\n+13462487799\,\,629888022# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\nMeeting ID: 629 888 022\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n629888022@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 629 888 022 \n──────────

SUMMARY:Rodrigo Alonso (Durham U) "Geometry for Higgs Dynamics and Effective Field Theory"
DESCRIPTION:Abstract:\n\nThe three Nambu-Goldstone bosons in the longitudinal modes of the W and Z  together with the Higgs boson span a 4-dimensional manifold. The geometry of this manifold\, invariant under field re-parametrization\, encodes the scalar dynamics which are vastly unexplored at present. The small but finite curvature limit recovers the Standard Model and  corrections in its effective field theory. First order corrections in this framework encode widely different physics and serve to test and constrast the different facets of the SM and their correlation. \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/195991343 \nMeeting ID: 195 991 343 \nOne tap mobile\n+16699006833\,\,195991343# US (San Jose)\n+13462487799\,\,195991343# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\nMeeting ID: 195 991 343\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n195991343@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 195 991 343 \n────────── \n

SUMMARY:Seljak\, Modi\, Boehm (RPM)
DESCRIPTION:Uros Seljak\, Chirag Modi\, Vanessa Boehm (LBL/Berkeley)\nHow deadly is COVID-19?  A time series analysis of Italy mortality data\n\nAbstract:\n\nA counterfactual analysis of 2020 mortality data reported from towns in Italy\, with data from the previous five years as control\, reveals a large excess of deaths in March 2020. The analysis shows a good agreement with reported COVID-19 mortality for age<70 years\, but an excess in total mortality increasing with age above 70 years\, suggesting there is a large population of predominantly old people missing from  the official fatality statistics. We estimate that the number of COVID-19 deaths in Italy is 52\,000 $\pm$ 2000 as of April 18 2020\, more than a factor of 2 higher than the official number. We determine infection fatality rate (IFR) lower bound of 0.84% for Lombardia and infection rate of 23% for Lombardia\, a factor of 35 above the number of positive tests. The infection rate for Bergamo province is 63%\, suggesting herd immunity has been reached there. The analysis can help predict corresponding numbers in USA: we predict 0.5% lower bound on IFR for NYC and Santa Clara county. We observe that the COVID-19 mortality tracks closely the overall mortality of the underlying population\, explaining why we see so many more deaths below age of 65 as a fraction of total in NYC relative to Italy. \nSlides \nWatch Video

DESCRIPTION:Abstract: \n\nThe American Physical Society’s Division of Particles and Fields is gearing up for its next community planning process (for historical reasons\, called Snowmass).  This process will occur over the next year and culminate in a 10 year plan (with a 20 year vision) for the future.  It is critical for us to provide input to this process\, which will ultimately inform the funding agencies about our community’s priorities for the future.  In this talk\, I will briefly introduce the various frontiers of the 2021 Snowmass process and will then mostly focus on the Computational Frontier and its connection to the other frontiers.  In particular\, this is an interesting time for computation with significant big data tools and infrastructure being developed by the broader scientific and industrial communities and with the advent of new (not part of the last Snowmass!) technologies like deep learning and quantum computing.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95017728528 \nMeeting ID: 950 1772 8528\nOne tap mobile\n+12532158782\,\,95017728528# US (Tacoma)\n+13017158592\,\,95017728528# US (Germantown) \nDial by your location\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)\n+1 646 558 8656 US (New York)\n+1 669 900 6833 US (San Jose)\nMeeting ID: 950 1772 8528\nFind your local number: https://lbnl.zoom.us/u/adExQ72UHW \nJoin by SIP\n95017728528@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: 950 1772 8528 \n──────────

SUMMARY:Ben Nachman (LBNL) "Modeling final state radiation on a quantum computer"
DESCRIPTION:Abstract: \nParticles produced in high energy collisions that are charged under one of the fundamental forces will radiate proportionally to their charge\, such as photon radiation from electrons in quantum electrodynamics. At sufficiently high energies\, this radiation pattern is enhanced collinear to the initiating particle\, resulting in a complex\, many-body quantum system. Classical Markov Chain Monte Carlo simulation approaches work well to capture many of the salient features of the shower of radiation\, but cannot capture all quantum effects. I will show how quantum algorithms are well-suited for describing the quantum properties of final state radiation. In particular\, I will describe a polynomial time quantum final state shower that accurately models the effects of intermediate spin states similar to those present in high energy electroweak showers. The algorithm is explicitly demonstrated for a simplified quantum field theory on a quantum computer.   One of the greatest challenges for current quantum computers is their significant noise.  I will present new techniques for mitigating both readout noise and gate error noise.  Readout errors are equivalent to detector effects in high energy physics (HEP) and I will show how building a bridge between fields can improve quantum computing in general\, not only for HEP.  For gate error mitigation\, I have proposed a new technique that can achieve a better precision than existing methods with a significantly reduced quantum complexity.   Finally\, I will discuss future directions at the interface between quantum computing and high energy physics.  See 1901.08148\, 1904.03196\, 1910.00129\, and 2003.04941 for details.\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/99636650720 \nMeeting ID: 996 3665 0720\nOne tap mobile\n+16465588656\,\,99636650720# US (New York)\n+16699006833\,\,99636650720# 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: 996 3665 0720\nFind your local number: https://lbnl.zoom.us/u/acaVi4S1v4 \nJoin by SIP\n99636650720@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: 996 3665 0720 \n──────────

SUMMARY:Hitoshi Murayama (LBNL/UCB)"International Linear Collider"
DESCRIPTION:ABSTRACT: \nHaving discovered the Higgs boson without obvious new particles at the Large Hadron Collider\, precision study of the Higgs boson at a Higgs factory is the obvious strategy at the energy frontier. I will review basic motivation and various options for the Higgs factory\, and discuss ILC in this context. I will also discuss some recent political developments.
