Description
The discovery of the lepton-number-violating neutrinoless double-beta decay process will prove that neutrinos are Majorana fermions. The Large Enriched Germanium Experiment for Neutrinoless double-beta Decay (LEGEND) project will search for this decay in $^{76}\mbox{Ge}$. In its first phase — LEGEND-200 — $200~\mbox{kg}$ of $^{76}\mbox{Ge}$-enriched high-purity germanium detectors will be deployed in a liquid-argon cryostat. It is under construction at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The first phase has a background goal of <0.6 counts/(FWHM t y), which yields a 3σ half-life discovery sensitivity beyond $10^{27}$ years. The second phase — LEGEND-1000 — will comprise 1000 kg of enriched germanium detectors. It will be sited deep underground with SNOLAB as the baseline host. LEGEND-1000 will have a discovery sensitivity beyond $10^{28}$ years. In this talk, I will give an overview of the LEGEND project.
