Results from the LEGEND-200 experiment in the search for neutrinoless double beta decay

The discovery of Neutrinoless double beta decay (0νββ) would provide unambiguous evidence for the Majorana nature of neutrinos, lepton number non-conservation and a measurement of the absolute neutrino mass scale. The Large Enriched Germanium Experiment for Neutrinoless ββ decay (LEGEND) is a phased search for 0νββ in the ⁷⁶Ge isotope with enriched high-purity germanium (HPGe) detectors. The LEGEND experiment brings together the innovation and expertise from its very successful, ⁷⁶Ge-based predecessors, GERDA and MAJORANA DEMONSTRATOR. The first phase, LEGEND-200, located at LNGS, Italy, is presently acquiring physics data. With an exposure of 1 ton-year and a background index in the region of interest of less than 2 x 10^-4 cts/(keV kg yr), LEGEND-200 will reach a discovery sensitivity of a half-life of 10²⁷ years.

This talk will present an overview of the LEGEND experiment, highlighting recent results from the ongoing LEGEND-200 phase and discussing future directions in the upcoming LEGEND-1000 phase.
