SUMMARY:Boryana Hadzhiyska (Harvard) "Uncovering physics from Stage-IV cosmological experiments with accurate galaxy models"
DESCRIPTION:Abstract:\nOver the next few years\, cutting-edge cosmological experiments such as DESI\, Rubin and CMB-S4 will provide an exquisite probe of the accelerated expansion of the Universe\, structure formation\, and general relativity\, and thus bring us closer to revealing the nature of dark energy\, dark matter\, inflation and neutrinos. One of the most critical issues with these experiments will be the connection between observed galaxies and the underlying matter field. My research program offers a viable path for constructing accurate models of the galaxy-matter connection and applying them to observational analysis\, with the goal of recovering the missing pieces of our cosmological model. In particular\, I will share my contributions to the development of state-of-the-art cosmological simulations and analysis tools and propose readily reachable goals for extracting cosmological information from the ongoing DESI and CMB experiments. Future breakthroughs will likely be the product of collaborative efforts across all of cosmology\, galaxy formation and particle physics. My broad-scaled research proposal will bring together diverse ideas and aid LBNL science goals at the crossroads of cosmological discovery. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96671323188?pwd=TVZ2WHZUcjgzMzhKV0sxQys3SUY5UT09 \nMeeting ID: 966 7132 3188\nPasscode: 657990\nOne tap mobile\n+16699006833\,\,96671323188#\,\,\,\,*657990# US (San Jose)\n+12532158782\,\,96671323188#\,\,\,\,*657990# 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 DC)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 966 7132 3188\nPasscode: 657990\nFind your local number: https://lbnl.zoom.us/u/ad4weom8dG \nJoin by SIP\n96671323188@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: 966 7132 3188\nPasscode: 657990 \n──────────

SUMMARY:Brendon Aurele Bullard (Harvard) “Toward Precision Measurements of the Higgs Yukawa Couplings” 
DESCRIPTION:Abstract: \nWith the discovery of the Higgs boson in 2012\, high energy physics has entered an era in which all fundamental particles predicted by the Standard Model have been observed. With no conclusive observations of physics beyond the Standard Model\, precision tests of the properties of the Higgs boson are key to find indications of new physics. I will discuss the program of precision measurements of the Higgs Yukawa coupling strengths with the ATLAS experiment\, focusing on those of the muon and top quark. I will give an overview of the search for Higgs decays in the dimuon channel with an emphasis on the novel use of quark/gluon tagging in an ATLAS Higgs measurement. Secondly\, I will present the status and outlook for the joint measurement of ttW and ttH production in multi-lepton final states with an emphasis on ttW modeling\, fake lepton estimation\, and profile-likelihood unfolding. Finally\, I will discuss the importance of the High Luminosity LHC for these physics goals in terms of sensitivity projections and the extension of tracking instrumentation provided by the ATLAS ITk upgrade. \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/95034216019?pwd=ZHNzZE0wcFBmdDczUTdpenBNZ0NNZz09 \nMeeting ID: 950 3421 6019\nPasscode: 999283\nOne tap mobile\n+16699006833\,\,95034216019#\,\,\,\,*999283# US (San Jose)\n+13462487799\,\,95034216019#\,\,\,\,*999283# 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 DC)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 950 3421 6019\nPasscode: 999283\nFind your local number: https://lbnl.zoom.us/u/adAIBZwhD4 \nJoin by SIP\n95034216019@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: 950 3421 6019\nPasscode: 999283 \n──────────

SUMMARY:Miao HU (MIT) “Vector Boson Scattering in the Post-Higgs-Boson-Discovery Era”
DESCRIPTION:Abstract:
  \nThe observation of a Higgs boson with a mass of about 125 GeV confirmed the nature of the electroweak symmetry breaking (EWSB) predicted by the standard model of particle physics\, establishing that the W and Z gauge bosons acquire their mass via the Higgs mechanism. However\, the discovered Higgs boson might not be the lone player responsible for EWSB. Further insights into the Higgs and the gauge bosons mutual- and self-couplings can be obtained from measurements of vector boson scattering (VBS) processes. \nIn this talk\, I will present the study of same-sign WW\, WZ\, and ZZ boson pair productions in association with two jets with data collected by the CMS detector. The effort led to the most precise measurement of the EW same-sign WW cross section to date and the first experimental observation of the EW WZ production. It also formed the basis for the first measurements of the polarized VBS. Interpretations beyond the standard model\, including the constraints on the structure of quartic vector boson interactions in the framework of effective field theory\, will also be discussed. \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/98462347467?pwd=RjB6dkJPUUpkdnZQd1E5Y0dlcDdaQT09 \nMeeting ID: 984 6234 7467\nPasscode: 652418\nOne tap mobile\n+16699006833\,\,98462347467#\,\,\,\,*652418# US (San Jose)\n+13462487799\,\,98462347467#\,\,\,\,*652418# 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 DC)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 984 6234 7467\nPasscode: 652418\nFind your local number: https://lbnl.zoom.us/u/acEKgxLvBN \nJoin by SIP\n98462347467@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: 984 6234 7467\nPasscode: 652418 \n──────────

SUMMARY:Maria Mironova (Oxford)  “First Direct Constraint on the Higgs-Charm Coupling and its Expected Evolution with the ATLAS Detector Upgrade”
DESCRIPTION:Abstract:
 \nThe coupling of the Higgsboson to charm quarks has eluded experimental observation since the Higgs boson discovery in 2012. At present\, this is the largest contribution to possibleHiggs boson decays that is not experimentally verified. However\, this measurement is crucial to shed light on the fundamental coupling of the Higgs boson to second-generation quarks. This seminar highlights the recent search for Higgs boson decays into a pair of charm quarks\, produced in association with a vector boson\, using the data collected by the ATLAS detector between 2015 and 2018.This measurement sets the first direct limit on the Higgs boson coupling to charm quarks \nWith the upgrade to High-Luminosity LHC (HL-LHC)\, a significant improvement to this measurement is expected due to the increased size of the dataset as well as the upgrade of the ATLAS Inner Tracker (ITk). A new pixel detector system will improve resolution\, increasing the identification efficiency of charm quarks. However\, the detector will have to cope with higher data rates and withstand higher levels of radiation. The ITk pixel upgrade\, particularly the characterisation of the pixel readout chips\, and the expected precision of the measurement of the Higgs boson coupling to charm quarks at the HL-LHC are discussed. \n \n \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/99938871022?pwd=YjZ5azNyaUtVV2FVTWNEZkJUTmc4Zz09\n\nMeeting ID: 999 3887 1022\nPasscode: 872514\nOne tap mobile\n+16699006833\,\,99938871022#\,\,\,\,*872514# US (San Jose)\n+12532158782\,\,99938871022#\,\,\,\,*872514# US (Tacoma)\n\nDial by your location\n        +1 669 900 6833 US (San Jose)\n        +1 253 215 8782 US (Tacoma)\n        +1 346 248 7799 US (Houston)\n        +1 646 558 8656 US (New York)\n        +1 301 715 8592 US (Washington DC)\n        +1 312 626 6799 US (Chicago)\nMeeting ID: 999 3887 1022\nPasscode: 872514\nFind your local number: https://lbnl.zoom.us/u/aeEwdvaKic\n\nJoin by SIP\n99938871022@zoomcrc.com\n\nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (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: 999 3887 1022\nPasscode: 872514\n\n\n──────────

SUMMARY:Vetri Velan (UC Berkeley) “The Present and Future of Dark Matter Direct Detection”
DESCRIPTION:Abstract:
  \nDark matter is one of the primary unsolved problems in modern particle physics. Since the late 1980s\, physicists have been trying to directly detect dark matter particles passing through the Earth\, typically by searching for nuclear recoils. This search has been unsuccessful so far\, but I will discuss recent advancements and upcoming technologies that offer a promising path forward. First\, I will present xenon time projection chambers\, including the LUX and LUX-ZEPLIN experiments\, as the best strategy for detecting Weakly Interacting Massive Particles (WIMPs). I will explain how understanding energy deposition in liquid xenon allows us to test the remaining WIMP parameter space\, and I will discuss recent data-driven and simulation-driven advancements in this field. Second\, I will discuss calorimetry as a tool for probing dark matter models below the WIMP scale\, with masses on the order of 1-1000 MeV/c2. I will describe the TESSERACT project\, using transition-edge sensors to achieve unprecedented sensitivity to a variety of dark matter interactions. \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/99788515717?pwd=YXhCSXRFSGZhZlE3dEJLeFRTNGF0UT09 \nMeeting ID: 997 8851 5717\nPasscode: 113722\nOne tap mobile\n+16699006833\,\,99788515717#\,\,\,\,*113722# US (San Jose)\n+13462487799\,\,99788515717#\,\,\,\,*113722# 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 DC)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 997 8851 5717\nPasscode: 113722\nFind your local number: https://lbnl.zoom.us/u/aibvGbITC \nJoin by SIP\n99788515717@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: 997 8851 5717\nPasscode: 113722 \n──────────

SUMMARY:Field Rose Rogers (MIT) "The GAPS Antarctic Balloon Experiment: Low-energy Antinuclei for Dark Matter Detection"
DESCRIPTION:Abstract:   \n\n\n\n\n\n\nDespite overwhelming evidence of abundant dark matter in the Universe\, the nature of this material remains a mystery. The General Antiparticle Spectrometer (GAPS) is an upcoming NASA Antarctic balloon mission to search for signatures of dark matter annihilation or decay in the fluxes of low-energy (<0.25 GeV/n) cosmic antinuclei. GAPS will produce a precision cosmic antiproton spectrum extending to an unexplored low-energy regime\, with sensitivity to light dark matter models\, primordial black holes\, and cosmic-ray propagation. GAPS will also either provide the first unambiguous detection of a cosmic-ray antideuteron or exclude the viable dark matter models that predict a low-energy antideuteron flux orders of magnitude above the astrophysical background. To identify these rare low-energy antinuclei while rejecting the abundant positive- nucleus backgrounds\, GAPS pioneers a novel exotic atom-based particle identification technique\, which relies on a system of >10 m2 of large-area high-temperature lithium-drifted silicon (Si(Li)) detectors. I will discuss the GAPS science program\, with a special emphasis on the exotic atom method of particle identification and the Si(Li) detectors that are central to its success. \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/92582314131?pwd=djVvMUp5US9zd2tKT0s3cDdBVTY2QT09 \nMeeting ID: 925 8231 4131\nPasscode: 234326\nOne tap mobile\n+16699006833\,\,92582314131#\,\,\,\,*234326# US (San Jose)\n+13462487799\,\,92582314131#\,\,\,\,*234326# 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 DC)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 925 8231 4131\nPasscode: 234326\nFind your local number: https://lbnl.zoom.us/u/acbbUKT6Fg \nJoin by SIP\n92582314131@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: 925 8231 4131\nPasscode: 234326 \n──────────

SUMMARY:Afroditi Papadopolou (Massachusetts Institute of Technology) Lepton-Nucleus Scattering Constraints For Neutrino Interactions And Oscillations
DESCRIPTION:Abstract: \nNeutrinos exist in one of three types or “flavors” (νe \,νµ or ντ )\, which oscillate from one to another when propagating through space. This phenomenon is one of the few that cannot be described using the Standard Model of particle physics and its study can thus provide new insight into the nature of our universe. As neutrinos interact only via the weak force\, they are experimentally detected only following their interactions with atomic nuclei. Our understanding of such interactions is crucial for measuring neutrino oscillations. In this talk I will review key open questions in the study of neutrino oscillations that drive the need for improved understanding of neutrino-nucleus interactions. I will then present our studies of such interactions using both neutrino and electron beams with the MicroBooNE and CLAS detectors and their impact on next-generation high-precision neutrino oscillation measurements with the DUNE and Hyper-Kamiokande experiments. \n\n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98561784665?pwd=MGtaM3Q4bVREZUMyM2hROWxHS0VPUT09 \nMeeting ID: 985 6178 4665\nPasscode: 573951\nOne tap mobile\n+16699006833\,\,98561784665#\,\,\,\,*573951# US (San Jose)\n+13462487799\,\,98561784665#\,\,\,\,*573951# 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 DC)\nMeeting ID: 985 6178 4665\nPasscode: 573951\nFind your local number: https://lbnl.zoom.us/u/aci5dxJ6xq \nJoin by SIP\n98561784665@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: 985 6178 4665\nPasscode: 573951 \n──────────

SUMMARY:Alissa Monte (UCSB) "Using Active Vetoes and Hydrogen Doping to Strengthen Dark Matter Discovery Potential with Xenon"
DESCRIPTION:Alissa Monte (UCSB) “Using Active Vetoes and Hydrogen Doping to Strengthen Dark Matter Discovery Potential with Xenon”\nAbstract: The fact that 85% of the gravitating mass in the universe is invisible is one of the biggest unsolved mysteries in fundamental physics today. If this dark matter was not present\, galaxies would fly apart and the universe would not develop the right amount of structure at the right time for you to exist and attend this RPM. Despite its abundance\, dark matter has yet to be directly detected in experiments on Earth. Why? The possible mass range for a dark matter particle extends from a fraction of the proton mass to the mass of a typical protein\, and these particles are thought to interact very weakly with normal matter. In fact\, potential dark matter interactions summed over the lifetime of a direct detection experiment would be swamped by the radioactivity of a single banana. I will talk about the future of the LUX-ZEPLIN (LZ) experiment with a focus on its veto systems\, which will be critical to ensure the quality of a future detection or to set the strongest limits possible. I will also talk about an exciting new idea to increase the sensitivity of LZ to low mass dark matter and spin-dependent interactions by doping its xenon with a light element like hydrogen. Finally\, I will motivate the need for active veto systems and hydrogen-capable cryogenics in a future G3 detector. \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/98831300746?pwd=c2RmMHhSZWFCOVl1elZOYXEyMGhhZz09 \nMeeting ID: 988 3130 0746\nPasscode: 373181\nOne tap mobile\n+16699006833\,\,98831300746#\,\,\,\,*373181# US (San Jose)\n+12133388477\,\,98831300746#\,\,\,\,*373181# 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+1 346 248 7799 US (Houston)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\n+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\n+1 253 215 8782 US (Tacoma)\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: 988 3130 0746\nPasscode: 373181\nFind your local number: https://lbnl.zoom.us/u/acJCraBN27 \nJoin by SIP\n98831300746@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: 988 3130 0746\nPasscode: 373181 \n──────────

SUMMARY:RPM - Physics Division | Aaron Manalaysay (LBNL) "Xe: The Element Designed to Detect Dark Matter"
DESCRIPTION:Abstract:  \nDespite nearly four decades of direct searches\, the identity of dark matter in the universe is still unknown.  The hunt for dark matter is especially alluring because\, not only is this abundant substance extremely elusive\, it also holds promise: we must invoke physics beyond the Standard Model to explain its existence.  The search for the WIMP\, one of the most popular and well-motivated candidates for dark matter\, has been dominated by experiments that utilize liquid xenon.  I will explain exactly how and why this detection medium has become so important and so versatile in this search.  LBNL has been at the center of this work\, with the former world-leading LUX experiment and as the lead-lab of the current LZ experiment.  I will discuss the design and construction of LZ\, its present\, and an idea for its future in which its sensitivity to low-mass dark matter is greatly enhanced by doping the Xe. \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/94456138734?pwd=eEl4MGpKZnR2QUxscU50dENxd2d2Zz09 \nMeeting ID: 944 5613 8734\nPasscode: 519139\nOne tap mobile\n+12133388477\,\,94456138734#\,\,\,\,*519139# US (Los Angeles)\n+16692192599\,\,94456138734#\,\,\,\,*519139# US (San Jose) \nDial by your location\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\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+1 971 247 1195 US (Portland)\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)\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)\nMeeting ID: 944 5613 8734\nPasscode: 519139\nFind your local number: https://lbnl.zoom.us/u/aehUb9y6HH \nJoin by SIP\n94456138734@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: 944 5613 8734\nPasscode: 519139 \n──────────

SUMMARY:Scott Kravitz (LBNL) "Pushing Dark Matter Detection to the Limit with Machine Learning and Solid Xenon"
DESCRIPTION:Abstract: \nDiscovering the particle properties of dark matter is a global undertaking\, necessitating many experimental approaches to cover the vast range of possible models. Massive particles such as WIMPs remain leading candidates\, and may be within the reach of state-of-the-art direct detection experiments such as the recently-commissioned xenon-based LZ detector. I will present efforts to use machine learning in xenon detectors to improve data quality\, reduce backgrounds\, make analysis faster and more flexible\, and expand the range of physics models that LZ can effectively probe. Looking beyond this generation of experiments\, continued improvement in dark matter sensitivity at the current rate is likely to require more creative solutions than simply increasing detector size. In the second part of my talk\, I will discuss the possibilities for upgrading LZ after its completion\, including using the novel solid xenon time projection chamber technology I have helped develop\, to achieve an experiment where solar neutrinos form the dominant background.\n\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/97609839371?pwd=blZGa1VzdlZHaGhHRFZibVY4Y0FrUT09 \nMeeting ID: 976 0983 9371\nPasscode: 481493\nOne tap mobile\n+16692192599\,\,97609839371#\,\,\,\,*481493# US (San Jose)\n+16699006833\,\,97609839371#\,\,\,\,*481493# US (San Jose) \nDial by your location\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\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+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\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)\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)\nMeeting ID: 976 0983 9371\nPasscode: 481493\nFind your local number: https://lbnl.zoom.us/u/aenZeWTLp5 \nJoin by SIP\n97609839371@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: 976 0983 9371\nPasscode: 481493 \n──────────

SUMMARY:Kirit Karkare (U.Chicago) "Pushing the Limits of Cosmology with Next-Generation Millimeter-Wave Telescopes"
DESCRIPTION:ABSTRACT:\nWhile the Lambda-CDM cosmological model is remarkably effective at describing the Universe and its evolution as a whole\, foundational questions remain. Where did the primordial fluctuations come from and why were they so uniform? What is causing the present-day accelerated expansion? What is the mass of the neutrino? Maps of large-scale structure at different epochs can address these questions. I will present the latest results from the BICEP/Keck cosmic microwave background experiment\, which is searching for B-mode polarization from an inflationary expansion at the earliest moments of time. I will focus on my work calibrating the instrument and controlling systematics\, and how current experiments are informing the design of the future CMB-S4 experiment which will test large classes of physically-motivated inflation models. I will then discuss mm-wave line intensity mapping — a new cosmological probe for measuring large-scale structure well into the first billion years of the Universe — and how future instruments using on-chip spectrometers such as SPT-SLIM could transform our understanding of cosmological physics.\n\n\nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96224978136?pwd=eGZCa1g4Y1NHcEN1ZmxPRHNVU0RnZz09 \nMeeting ID: 962 2497 8136\nPasscode: 593459\nOne tap mobile\n+12133388477\,\,96224978136#\,\,\,\,*593459# US (Los Angeles)\n+16692192599\,\,96224978136#\,\,\,\,*593459# US (San Jose) \nDial by your location\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\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+1 971 247 1195 US (Portland)\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)\n+1 646 518 9805 US (New York)\nMeeting ID: 962 2497 8136\nPasscode: 593459\nFind your local number: https://lbnl.zoom.us/u/adXBjo1l7V \nJoin by SIP\n96224978136@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: 962 2497 8136\nPasscode: 593459 \n──────────

SUMMARY:Joint Special RPM and INPA Seminar | Chelsea Bartram (U of Washington) "Combing the Cosmos: A Deep Dive into the Nature of (Dark) Matter and Fundamental Symmetries"
DESCRIPTION:Abstract:\nOne of the most striking mysteries in modern astrophysics manifests itself as an absence of matter needed to form a narrative consistent with our current understanding of the universe. A promising candidate for the so-called “dark matter” is the axion\, whose wave-like nature requires unique technology to detect. The Axion Dark Matter eXperiment (ADMX) leverages the inverse Primakoff effect to search for axions using an ultra-low noise receiver chain and microwave cavity in a strong magnetic field. If discovered\, the axion could not only solve the dark matter problem but also resolve the Strong CP problem. Fundamental symmetries have been at the center of many deep astrophysical questions. As such\, they have served as a driving force behind my research\, motivating my graduate search for CP- and CPT-violation in the lepton sector\, as well as my post-doctoral work in axion dark matter. I present my prior research and explain how it fits into my larger ambition to understand the large-scale structure and composition of the universe with CMB-S4.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94989648361?pwd=d3R5M1Y3QXBLQW1CVy82RHdGSVR3dz09 \nMeeting ID: 949 8964 8361\nPasscode: 453787\nOne tap mobile\n+16699006833\,\,94989648361#\,\,\,\,*453787# US (San Jose)\n+12133388477\,\,94989648361#\,\,\,\,*453787# 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: 949 8964 8361\nPasscode: 453787\nFind your local number: https://lbnl.zoom.us/u/acZdUt3D47 \nJoin by SIP\n94989648361@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: 949 8964 8361\nPasscode: 453787 \n──────────

SUMMARY:Kevin Crowley (UCB) "The View From Down Here: Ground-Based Measurements of the Cosmic Microwave Background from the Atacama Desert"
DESCRIPTION:Abstract:\n\nThe study of the Cosmic Microwave Background (CMB) anisotropies has become a percent-level science constraining the accepted cosmological model ΛCDM. The most powerful measurements thus far have been made from space\, but observations from the Earth’s surface can be made at higher resolution\, with higher detector count\, and with iterative upgrades to the instruments. One key goal of recent upgrades has been recovering the large angular-scale polarization signal that could reveal the signature of inflation in the early universe. The current generation of ground-based telescopes have developed new technologies\, including polarization-modulator systems\, kilopixel focal plane arrays\, and highly-multiplexed detector readout\, all with the goal of enabling sensitivity while controlling systematic errors in the challenging environment of polarization measurements under the atmosphere. In this talk\, I will describe my efforts in these areas of instrumentation development and my experiences pushing for sensitivity while pondering just what lies below the noise in CMB experiments observing from the Atacama Desert. I will also highlight the ways that future experiments\, including the under-construction Simons Observatory and the exciting prospect of CMB-S4\, will lay a path toward the ultimate goal of fully exploring the physics in the CMB from terra firma. \nhttp://physics.lbl.gov/rpm/index.php/events/If 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.Join Zoom Meeting\nhttps://lbnl.zoom.us/j/94763254514?pwd=OTdvellKbHNFUGNJUWpHUGtKTTdPUT09 \nMeeting ID: 947 6325 4514\nPasscode: 894772\nOne tap mobile\n+16692192599\,\,94763254514#\,\,\,\,*894772# US (San Jose)\n+16699006833\,\,94763254514#\,\,\,\,*894772# US (San Jose) \nDial by your location\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 720 928 9299 US (Denver)\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+1 470 381 2552 US (Atlanta)\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)\nMeeting ID: 947 6325 4514\nPasscode: 894772\nFind your local number: https://lbnl.zoom.us/u/adMiQV0p1t \nJoin by SIP\n94763254514@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: 947 6325 4514\nPasscode: 894772 \n──────────

SUMMARY:Roger O'Brient (U. Washington) "Superconducting Detectors for Cosmology and Ultra-High Energy Physics"
DESCRIPTION:Abstract:\nThe BICEP program has thus far constrained the tensor scalar ratio r<0.036\, approaching the gravitational lensing floor.  This was possible in large part because of innovations in detector technology at JPL.  In my talk\, I will describe the antenna-coupled TES bolometers used in BICEP and how JPL as played this vital role in the project.  I’ll provide some context of how they fit into similar technologies from peer institutions\, and how some of the lessons learned in BICEP may be transferable to CMB S4.  Finally\, I’ll describe how the next generation of resonator-based detectors will enable future missions and experiments in far-IR and millimeter wave astrophysics.\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\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/97074529102?pwd=K2FyOUI4OGFrOWswT1ZYZTlzTzV3UT09 \nMeeting ID: 970 7452 9102\nPasscode: 674004\nOne tap mobile\n+16699006833\,\,97074529102#\,\,\,\,*674004# US (San Jose)\n+12133388477\,\,97074529102#\,\,\,\,*674004# 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+1 346 248 7799 US (Houston)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\n+1 971 247 1195 US (Portland)\n+1 206 337 9723 US (Seattle)\n+1 253 215 8782 US (Tacoma)\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)\n+1 646 518 9805 US (New York)\n+1 646 558 8656 US (New York)\n+1 651 372 8299 US (Minnesota)\nMeeting ID: 970 7452 9102\nPasscode: 674004\nFind your local number: https://lbnl.zoom.us/u/ayA29i6Kr \nJoin by SIP\n97074529102@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: 970 7452 9102\nPasscode: 674004 \n──────────

SUMMARY:Kaori Fuyuto (LANL) "A Cross-Frontier Quest to Reveal the Origin of the Universe"
DESCRIPTION:Abstract: \n\n\nThe Standard Model (SM) is the most well-tested theory of elementary particles that make up the known Universe. However\, there are still some major puzzles that cannot be accounted for by the SM in our Universe\, e.g.\, matter-antimatter asymmetry of the Universe and the origin of neutrino mass. Solving these puzzles require physics beyond the SM (BSM)\, which is searched for in a variety of frontiers today. In this talk\, I will discuss how BSM physics\, which could provide solutions to the above mysteries\, can be probed at both energy and intensity frontiers\, i.e.\, the Higgs coupling measurements in collider experiments and LFV searches at the Electron-Ion Collider.\n\n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting.Join Zoom Meeting\nhttps://lbnl.zoom.us/j/94456986488?pwd=T2Y5MnZLdW1aenJrVWJVcmwvMTZ3QT09 \nMeeting ID: 944 5698 6488\nPasscode: 173732\nOne tap mobile\n+16692192599\,\,94456986488#\,\,\,\,*173732# US (San Jose)\n+16699006833\,\,94456986488#\,\,\,\,*173732# US (San Jose) \nDial by your location\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 720 928 9299 US (Denver)\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+1 301 715 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)\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)\nMeeting ID: 944 5698 6488\nPasscode: 173732\nFind your local number: https://lbnl.zoom.us/u/aYqcyDruC \nJoin by SIP\n94456986488@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: 944 5698 6488\nPasscode: 173732 \n──────────

SUMMARY:Nicholas Rodd (CERN) "Looking Beyond Dark Matter in Axion Haloscopes"
DESCRIPTION:Abstract:\nThe coming decade will bring dramatic improvement in the axion dark-matter program as new experimental designs move beyond the proof of principle stage. In this talk I will outline two signals beyond dark matter that these instruments could discover. The first is a population of relativistic axions that were produced in the early universe and persist as a residual Cosmic axion Background (CaB). The second is high-frequency gravitational waves; I will outline how exploiting an analogy between axion and gravitational-wave electrodynamics allows for axion haloscopes to be converted into gravitational-wave telescopes.\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/93382847475?pwd=T1ZkZXpJaDVPcS9RMzVTUUs5U1N3Zz09 \nMeeting ID: 933 8284 7475\nPasscode: 149179\nOne tap mobile\n+12133388477\,\,93382847475#\,\,\,\,*149179# US (Los Angeles)\n+16692192599\,\,93382847475#\,\,\,\,*149179# US (San Jose) \nDial by your location\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\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+1 470 250 9358 US (Atlanta)\n+1 470 381 2552 US (Atlanta)\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)\nMeeting ID: 933 8284 7475\nPasscode: 149179\nFind your local number: https://lbnl.zoom.us/u/aNjxTC2pd \nJoin by SIP\n93382847475@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: 933 8284 7475\nPasscode: 149179 \n──────────

SUMMARY:Gustavo Marques Tavares (UMD) "Dark Sector Signals from Extreme Astrophysical Environments"
DESCRIPTION:Abstract: \nDark sectors are well motivated extensions of the Standard Model that can address many of the most important open questions in particle physics\, such as the particle nature of dark matter\, origin of neutrino masses\, and the Higgs hierarchy problem. In many scenarios\, the interactions between the dark sector and the standard model can be very small. For extremely weak interactions\, the best strategy to search for these new states is to look for their signature in extreme astrophysical environments\, such as core-collapse supernovae and neutron star mergers. In this talk\, I will present new signatures that can be used to search for stable and unstable dark sector particles in extreme astrophysical systems\, covering a wide range of parameter space for masses in the MeV-GeV range. \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/93985344273?pwd=M0RPc3dZM1JpWllOb3lHWnNEamZwZz09 \nMeeting ID: 939 8534 4273\nPasscode: 125108\nOne tap mobile\n+12133388477\,\,93985344273#\,\,\,\,*125108# US (Los Angeles)\n+16692192599\,\,93985344273#\,\,\,\,*125108# US (San Jose) \nDial by your location\n+1 213 338 8477 US (Los Angeles)\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 602 753 0140 US (Phoenix)\n+1 720 928 9299 US (Denver)\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+1 646 558 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)\n+1 646 518 9805 US (New York)\nMeeting ID: 939 8534 4273\nPasscode: 125108\nFind your local number: https://lbnl.zoom.us/u/aVJYot3HB \nJoin by SIP\n93985344273@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: 939 8534 4273\nPasscode: 125108 \n──────────

SUMMARY:Pier Monni (CERN) "Taming the Complex Dynamics of Scattering Events"
DESCRIPTION:Abstract: \n\nThe pioneering investigation of the fundamental laws of nature at the Large Hadron Collider builds upon the interpretation ofcomplex scattering events. Our ability to identify small signals of elusive new phenomena therefore depends on accurate theoretical simulations which describe the evolution of the system from the few\nproduced in the high-energy scattering to the tens or hundreds of low-energy particles observed in the experimental detectors. In this talk\, I will discuss the main theoretical technology behind this endeavour\, that of event generators. I will present a number of recent theoretical innovations that will shape the creation of a new generation of tools\, essential to achieve the outstanding accuracy demanded by collider experiments.\n\n\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/96007374638?pwd=VGk3VXdZNVNCZXhCZHBhSVBTTkpnUT09 \nMeeting ID: 960 0737 4638\nPasscode: 335942\nOne tap mobile\n+16692192599\,\,96007374638#\,\,\,\,*335942# US (San Jose)\n+16699006833\,\,96007374638#\,\,\,\,*335942# US (San Jose) \nDial by your location\n+1 669 219 2599 US (San Jose)\n+1 669 900 6833 US (San Jose)\n+1 213 338 8477 US (Los Angeles)\n+1 720 928 9299 US (Denver)\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+1 301 715 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)\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)\nMeeting ID: 960 0737 4638\nPasscode: 335942\nFind your local number: https://lbnl.zoom.us/u/ac00PgASWv \nJoin by SIP\n96007374638@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: 960 0737 4638\nPasscode: 335942 \n──────────

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
