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──────────

SUMMARY:SPECIAL RPM-Berkeley Cosmology Seminar | Noah Weaverdyck (University of Michigan) "Controlling Systematics in Large-Scale Structure Surveys"
DESCRIPTION:Abstract: \nLarge-scale structure (LSS) surveys have exploded in size over the last few decades\, cataloguing the locations and shapes of hundreds of millions of galaxies. The unprecedented precision enabled by such datasets puts extraordinary demands on the control of systematic errors. In this talk\, I will discuss how extracting information from LSS surveys is complicated by systematics that enter the survey selection function\, outline several approaches to address these systematics\, and highlight important lessons for upcoming surveys.\n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting.Join Zoom Meeting\nhttps://lbnl.zoom.us/j/91399869562 \nMeeting ID: 913 9986 9562\nOne tap mobile\n+16699006833\,\,91399869562# US (San Jose)\n+12532158782\,\,91399869562# 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+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Washington D.C)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 913 9986 9562\nFind your local number: https://lbnl.zoom.us/u/akhID8uDJ \nJoin by SIP\n91399869562@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: 913 9986 9562 \n──────────

SUMMARY:Vinicius Mikuni (University of Zurich) "Machine learning as a tool for Standard Model measurements."
DESCRIPTION:Abstract: \nThe Standard Model of particle physics described the interactions between the elementary particles that compose our universe. To study these interactions\, protons collide at very high energies at the Large Hadron Collider\, generating hundreds of particles through every bunch crossing. In this talk\, I will present two measurements that probe different aspects of the Standard Model: the determination of the ttbb and bbH(bb) cross sections. I will show the challenges faced during data analysis and how modern machine learning methods can be used to improve the precision of these measurements.\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:Elliott Reynolds (University of Birmingham) "Searching for New Physics using the Higgs Boson and Machine Learning"
DESCRIPTION:Abstract: \n \nThe Higgs boson is the only fundamental spin-0 particle in the Standard Model (SM) of particle physics\, associated with an ever-present field that is the source of mass and linked to electroweak symmetry breaking\, making it a particle like no other. Its mass and spin provide us with the strongest indication yet that something is amiss with the SM\, and offer a unique window to probe the SM and new physics in its decays. This talk covers a broad range of searches sensitive to new physics in the Higgs sector using the ATLAS detector at the CERN LHC\, with an emphasis on the versatile role of novel machine learning techniques. The related physics prospects of the high-luminosity upgrade of the LHC and the ATLAS detector are also discussed.\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/97582336673 \nMeeting ID: 975 8233 6673\nOne tap mobile\n+16699006833\,\,97582336673# US (San Jose)\n+13462487799\,\,97582336673# 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: 975 8233 6673\nFind your local number: https://lbnl.zoom.us/u/arXhC3CAb \nJoin by SIP\n97582336673@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 8233 6673 \n──────────

SUMMARY:Mariel Pettee (Yale University) "The Search for VH (V → Leptons\, H → 𝜏𝜏) with the ATLAS Experiment in Run 2"
DESCRIPTION:Abstract: \n\nAs part of a comprehensive plan to investigate the many combinations of production and decay of the Standard Model Higgs boson using the full Run 2 ATLAS dataset at the LHC\, I will present a search for the SM Higgs boson produced in association with a leptonically-decaying vector boson (i.e. a W or Z boson) and decaying into a pair of tau leptons. Efficient identification of hadronically-decaying tau leptons at the trigger level is essential to this analysis\, so I will also discuss my technical work in deploying an RNN-based tau identification scheme in the ATLAS High-Level Trigger (HLT) in Run 2. Lastly\, I will show highlights of my independent AI work in leading teams of researchers across academia and industry to pioneer the state-of-the-art in AI-generated choreography using techniques including Variational Autoencoders (VAEs) and Graph Neural Networks (GNNs). \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/95547677630 \nMeeting ID: 955 4767 7630\nOne tap mobile\n+16699006833\,\,95547677630# US (San Jose)\n+12532158782\,\,95547677630# 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: 955 4767 7630\nFind your local number: https://lbnl.zoom.us/u/ady5iTj2aJ \nJoin by SIP\n95547677630@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: 955 4767 7630 \n──────────
