Abstract
The neutrinoless double beta decay (0νββ) is a hypothetical process which, if observed, would demonstrate the neutrino is a Majorana particle. This process beyond by the Standard Model, and violates lepton number. The LEGEND (Large Enriched Germanium Experiment for Neutrinoless Double beta decay) experiment searches for 0νββ in 76Ge, with goals of establishing a discovery sensitivity for a half-life of this nucleus beyond 1028 years. The first phase, LEGEND-200, is currently operational in a preliminary configuration at Laboratori Nazionali del Gran Sasso (LNGS) in Italy. In its next phase, LEGEND-1000 aims to achieve its target sensitivity beyond 1028 years. To achieve this sensitivity, it is necessary to complete a background-free measurement in the region of interest, through suppression of radiogenic and cosmogenic backgrounds. LEGEND employs many methods to meet this stringent goal including world-class radiopure material fabrication, cutting-edge electronics and signal processing, innovative analysis methods, and an advanced multi-system background veto.
