The CUPID Neutrinoless Double Beta Decay Experiment
The CUPID Neutrinoless Double Beta Decay Experiment is a groundbreaking research project aimed at detecting the elusive neutrinoless double beta decay process. This process, if observed, would provide evidence for the existence of a Majorana neutrino, a particle that is its own
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.
