SUMMARY:HYBRID TALK | Mengjiao Xiao (MIT) "In Search of Cosmic-Ray Antinuclei from Dark Matter with the GAPS Experiment"
DESCRIPTION:Abstract:\nThe origin of dark matter is a driving question of modern physics. Finding dark matter in the laboratory and elucidating its properties could revolutionize our understanding of the fundamental building blocks of the universe. The common challenges for dark matter searches in astrophysical signatures are large and uncertain backgrounds. The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment designed to identify low-energy cosmic antinuclei\, in particular antideuterons from dark matter annihilation or decay\, using the uniquely characterized atomic X-rays and charged particles from the decay of exotic atoms. With such a novel detection approach\, benefitting from a custom- d eveloped large- area silicon tracker and a large-acceptance Time-of-Flight system\, GAPS is sensitive to antideuterons and even antiheliums with the kinetic energy ≤0.25 GeV/n\, which should offer an essentially background-free region to probe many generic dark matter models. Additionally\, GAPS will collect a high-statistics antiproton spectrum in an unexplored energy range\, and open a sensitivity to cosmic antihelium. \nThe GAPS instrument consists of a tracker of >1000 custom Si(Li) detectors; a precision- timing\, large-area time-of-flight system; and a novel oscillating heat pipe thermal system. GAPS is currently under integration and preparing for the first Antarctic balloon flight in late 2023 while two follow-up flights are planned. This talk will present the science impact of the GAPS experiment\, while focusing on its custom-developed instrument technology\, including the design principle\, commissioning of the GAPS functional prototype\, integration and testing of GAPS full payload\, and the path forward to the initial flight. \n  \nhttp://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 917 8226 8585 \n
