double-beta decay experiments

Double-beta decay experiments investigate a rare nuclear process where an atom's nucleus emits two electrons and two neutrinos, transforming into a different element. Scientists are especially interested in a hypothetical version called neutrinoless double-beta decay, which, if observed, would suggest that neutrinos are their own antiparticles and provide insights into their fundamental nature. These experiments use highly sensitive detectors to observe and measure these decays in specific isotopes, helping physicists understand the properties of neutrinos and test the limits of the Standard Model of particle physics.
