Neutrinoless Double Beta Decay
Neutrinoless Double Beta Decay is a rare nuclear process that occurs when a nucleus emits two electrons but no neutrinos. This phenomenon is significant because it could provide evidence for the existence of Majorana particles, which are their own antiparticles. If observed, it would imply that neutrinos have mass and could help explain the matter-antimatter asymmetry in the universe.
Researchers are actively searching for this decay in various isotopes, such as tellurium-130 and germanium-76. Detecting neutrinoless double beta decay would have profound implications for particle physics and our understanding of the fundamental forces in nature.
