- The LEGEND collaboration is searching for the ultra-rare process of neutrinoless double beta decay in 76Ge. The discovery of this decay would establish that the neutrino is its own antiparticle, with far-reaching implications in explaining the matter-antimatter asymmetry in our universe. A ton-scale array of germanium detectors, fabricated with ultra-low background materials and operated in a scintillating liquid argon veto, can make a discovery at a half-life beyond $10^{28}$ years, more than an order-of-magnitude advance over current-generation experiments. The first stage, LEGEND-200, is under construction at LNGS, with detectors in production and commissioning data being analyzed. R&D for LEGEND-1000 is also underway, with an ultimate goal of reducing radioactive backgrounds at the 76Ge decay energy (2039 keV) to a world-leading < 0.03 cts/(FWHM-t-yr). In this work, I present the current outlook for LEGEND.
