LEGEND: The Large Enriched Germanium Experiment for Neutrinoless Double-Beta Decay
ORAL
Abstract
The lepton number violating process of neutrinoless double-beta decay might result from the physics beyond the Standard Model. The current generation of Ge-76 experiments, the \textsc{Majorana Demonstrator} and GERDA, lead the field in both the energy resolution and ultra-low background achieved. The next generation of experiments require increased mass and further reduction of backgrounds to maximize discovery potential. Building on the successes of the \textsc{Majorana} and GERDA, the LEGEND collaboration formed to pursue a tonne-scale Ge experiment, with discovery potential at a half-life beyond $10^{28}$ years. The collaboration aims to develop a phased neutrinoless double-beta decay experimental program, starting with a 200 kg of Ge detectors fabricated from enriched Ge using the existing GERDA infrastructure at LNGS. We describe the plans and physics reach of LEGEND
