Double beta decay: phenomenology and experiments

Abstract:

Double beta decay (DBD) is the rarest known type of radioactive decay, with the observed half-life of 10^18--10^25 years. Two kinds of double beta processes are predicted: one of them (observed) is the two-neutrino DBD. The second one -- the neutrinoless DBD -- is forbidden by the Standard Model, and has never been observed. I will discuss the reasons why this process is so important in the search for the New Physics beyond the Standard Model. The current status of  experiments will be reviewed.
