Event 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. The LEGEND experiment searches for the neutrinoless double-beta decay of Ge-76 with hundreds of kilograms of detectors. I’ll discuss LEGEND-200’s first results and LEGEND-1000’s projected discovery potential, as well as some of the machine learning-based analysis techniques my group is developing to make these experiments even more sensitive.
