Description
The search for neutrinoless double-beta decay is currently one of the
most compelling challenges in physics, with the potential to reveal the origin of the neutrino’s mass, demonstrate lepton number violation, and provide hints of the mechanism behind the matter anti-matter asymmetry we observe in our universe. Detecting this ultra-rare process, however, requires us to build very large detectors with very low background rates. Currently operating hundred-kilogram-scale experiments like CUORE, LEGEND-200 and the soon-to-come KamLAND2-Zen are beginning to probe the parameter space expected by minimal models of high-scale lepton number violation, and progress on ton-scale experiments is advancing quickly, with several collaborations aiming to begin
construction in the coming years. These experiments aim to achieve 3σ discovery sensitivity at 10^28 year half lives. I’ll give an overview of the current state of the field and the status of next-generation experiments.
