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──────────
