Description

The Large Enriched Germanium Experiment for Neutrinoless bb Decay (LEGEND) aims to search for neutrinoless double beta decay (0vbb) with a half-life sensitivity in the ${^{76}}$Ge isotope above T${_{1/2}}$ = 10${^{28}}$ years. The first phase, LEGEND-200, is currently operating and taking data with ~130 kg of high-purity enriched germanium detectors immersed in liquid argon, with an expected final configuration of ~200 kg of detectors. The second phase, LEGEND-1000, will be configured with up to 1000 kg of detectors, with a goal of acquiring 10 tonne-years of total exposure during data taking to meet the target sensitivity. In this talk, I will outline the LEGEND-200 analysis framework, highlight the latest results of the search for 0vbb in this phase, and discuss the future plans to continue improving the experimental program.
