The LEGEND-1000 Beyond Standard Model physics program
ORAL
Abstract
LEGEND-1000 is a proposed experiment to search for the neutrinoless double-beta decay of 76Ge with a half-life sensitivity of beyond 1028 years. It will be the successor of the operating LEGEND-200 experiment. LEGEND-1000 will deploy isotopically enriched high purity germanium detectors in a low-background liquid argon and water shield underground at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. LEGEND-1000’s low ionizing radiation backgrounds, low noise electronics, and advanced signal processing allow for searches for other Beyond Standard Model (BSM) physics, such as dark matter, solar axions, and exotic nuclear decays. It also allows tests of fundamental conservations laws and theories of quantum wave function collapse. This talk will review these searches in previous germanium experiments and discuss the future capabilities of LEGEND-1000 to probe BSM physics.
