The KamLAND-Zen Neutrinoless Double Beta Decay Experiment
The KamLAND-Zen Neutrinoless Double Beta Decay Experiment is a research project designed to study the phenomenon of neutrinoless double beta decay, a rare nuclear process that could provide insight into the nature of neutrinos and the origin of matter in the universe. The experiment
From Wikipedia
Neutrinoless double beta decay (0νββ) is a commonly proposed and experimentally pursued theoretical radioactive decay process that would prove a Majorana nature of the neutrino particle. To this day, it has not been found.
