Physics searches beyond neutrinoless double-beta decay with LEGEND-1000
ORAL
Abstract
LEGEND-1000 is a proposed experiment to search for the neutrinoless double-beta decay (NDBD) of the $^{76}$Ge isotope. It will use enriched high-purity germanium (HPGe) detectors deployed in an active liquid argon shield at a deep underground location. The HPGe detectors are based on the p-type point contact detectors successfully demonstrated in \textsc{Majorana} and GERDA. The low noise and low energy thresholds of these detectors, in addition to the low-background design of LEGEND-1000, provides a broad and rich program for searches of new physics other than neutrinoless double-beta decay. Examples include dark matter, axions, exotic nuclear decays, and tests of fundamental symmetries. This talk will review the LEGEND program and describe these other physics opportunities.
