SUMMARY:[Virtual] INPA Seminar Speaker: Erin Engelhardt ( University of North Carolina\, Chapel Hill)- Title: Searching for Neutrinoless Double-Beta Decay with LEGEND-200
DESCRIPTION:Date: January 17\, 2025 \nTime: 12:00 am – 1:00 pm \nLocation: Sessler Conference Room – 50A-5132 [Hybrid and In-Person] \nSpeaker: Erin Engelhardt ( University of North Carolina\, Chapel Hill) \nTitle:   Searching for Neutrinoless Double-Beta Decay with LEGEND-200 \nAbstract:  Neutrinoless double-beta decay (0νββ) is a theorized process where two neutrons decay into two protons and two electrons without emitting any antineutrinos. The existence of 0νββ would indicate the neutrino has a Majorana nature and thus acts as its own antiparticle. This process would violate lepton number conservation and provide a mechanism for explaining the observed matter/antimatter asymmetry. The Large Enriched Germanium Experiment for Neutrinoless ββ decay (LEGEND) is a phased 0νββ search in 76Ge using isotopically enriched high-purity germanium (HPGe) point contact detectors. The first phase\, LEGEND-200\, began operating in March 2023 with 142 kg of HPGe detectors and announced an updated half-life limit of 1.9 x 1026 yrs at the Neutrino 2024 conference. To achieve its sensitivity goals\, LEGEND-200 requires incredibly low background rates. Alpha and beta particles on the detector surfaces constitute a significant source of backgrounds in LEGEND. To mitigate these backgrounds\, a new pulse-shape discrimination technique for identifying surface events has been developed and implemented into the first LEGEND-200 analysis. In this seminar\, I will present an overview of the LEGEND-200 analysis and its first result. I will also discuss the performance and evaluation of the surface background rejection techniques used in LEGEND. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011 \nPasscode: 247722
