KamLAND-Zen

KamLAND-Zen is an experimental setup designed to search for a rare nuclear process called neutrinoless double beta decay, which, if observed, could reveal that neutrinos are their own antiparticles and help explain why the universe has more matter than antimatter. It uses a large detector filled with liquid scintillator, containing a small amount of xenon-136. When a double beta decay occurs, it produces a distinct energy signal detected by sensitive instruments. This experiment aims to improve our understanding of neutrino properties and fundamental physics beyond the Standard Model.
