Abstract
The search for the neutrinoless double beta (0νββ) decay is con- sidered the most promising way to prove the Majorana nature of neutrinos. The LEGEND (Large Enriched Germanium Detector for Neutrinoless ββ Decay) col- laboration aims at building a 1 ton 76Ge-based 0νββ experiment with 3σ half-life discovery sensitivity of 1028 years to fully span the inverted neutrino mass ordering region. Combining the efforts of previous Gerda and MAJORANA experiments, the LEGEND project will first proceed by deploying 200 kg of enriched HPGe de- tectors in the already existing Gerda facility at Laboratori Nazionali del Gran Sasso (LNGS) in Italy. With an exposure of 1 t·yr and a background index of 0.5 counts/(FWHM·t·yr), LEGEND-200 will reach a 3σ half-life discovery sensitivity for the 0νββ decay of 1027 yr. An overview of the LEGEND project together with the current status and preliminary performance of LEGEND-200 are presented in this work.
