Status of the LEGEND-200 Experiment

ORAL

Abstract



Observation of neutrinoless double-beta (0νββ) decay would show that the neutrino mass not only breaks lepton number conservation, but also B-L, the last remaining accidental symmetry of the Standard Model. LEGEND is searching for 0νββ decay in 76Ge using an array of enriched high-purity germanium detectors. In order to reach its target discovery sensitivity, LEGEND uses ultra-low background materials, pulse shape discrimination, and a liquid argon scintillation detector as an active veto. LEGEND-200, the first phase of the LEGEND program, is currently taking data at LNGS. This talk will summarize LEGEND-200 from its construction to its initial performance.
