SUMMARY:INPA SEMINAR Speaker: John (Jack) Smedley (U of Rochester)-Title: Measuring Neutrino Cross Sections on Argon with the ICARUS Detector
DESCRIPTION:Date: January 10\, 2025 \nTime: 12:00 am – 1:00 pm \nLocation: Sessler Conference Room – 50A-5132 [Hybrid and In-Person] \nSpeaker: John (Jack) Smedley (University of Rochester) \nTitle:  Measuring Neutrino Cross Sections on Argon with the ICARUS Detector \nAbstract:  ICARUS is a large liquid argon time projection chamber (LArTPC) operating at Fermilab as the far detector for the Short-Baseline Neutrino Program. ICARUS is also able to measure neutrino-argon interactions in the same energy range as the future long-baseline neutrino experiment DUNE via its off-axis position to the NuMI neutrino beam. Here we present progress toward the first cross-section measurements from ICARUS\, targeting events with one or more nucleons and zero mesons in the final state. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011 \nPasscode: 247722

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

SUMMARY:INPA Seminar Speaker: Alex Droster (UC Berkeley)-Title: Searching high and low for dark matter axions
DESCRIPTION:Date: January 31\, 2025 \nTime: 12:00 am – 1:00 pm \nLocation: Sessler Conference Room – 50A-5132 [Hybrid and In-Person] \nSpeaker: Alex Droster (UC Berkeley) \nTitle: Searching high and low for dark matter axions \nAbstract: After almost 50 years\, the axion remains the only mainstream solution to the non-observation of CP violation in the strong force. It is also a very attractive solution to the dark matter problem of the universe due to its long lifetime\, weak Standard Model couplings\, and production mechanisms in the early universe that generate cosmologically relevant density. However\, nearly half a century after its proposal\, the axion remains undiscovered. In this talk I will review experimental efforts across nine orders of magnitude in axion mass aimed at directly detecting this elusive particle\, focusing on the HAYSTAC and ALPHA experiments looking for high mass post-inflationary axions\, and DMRadio on the opposite end of the scale searching for very low mass GUT-scale axions. I will also describe the quantum enhancement techniques which have already enabled us to operate below the Standard Quantum Limit\, and strategies for extending these ultrasensitive searches to both higher and lower frequencies. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011 \nPasscode: 247722
