NPA Seminar: Julieta Gruszko, The University of North Carolina, Chapel Hill, "New Results from LEGEND-200"
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.
