Neutrinoless double beta decay information

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.^[1]^[2] To this day, it has not been found.^[2]^[3]^[4]

The discovery of neutrinoless double beta decay could shed light on the absolute neutrino masses and on their mass hierarchy (Neutrino mass). It would mean the first ever signal of the violation of total lepton number conservation.^[5] A Majorana nature of neutrinos would confirm that the neutrino is its own antiparticle.^[6]

To search for neutrinoless double beta decay, there are currently a number of experiments underway, with several future experiments for increased sensitivity proposed as well.^[7]
