Beta-beta decays and other rare processes

In my talk, I will present a status of various double beta decay experiments. Especially, I will focused on the various experimental approaches, the background of these experiments, their results or expected results on double-beta 2 and 0-neutrino half-lives and the corresponding limit on the effective neutrino mass.

1. Recent advances in neutrinoless double beta decay with energy density functional methods

Beta-beta decays and other rare processes

In this presentation I will summarize some recent calculations of the nuclear matrix elements (NME) for neutrinoless double beta decay performed within the energy density functional framework. In particular, I will focussed on the role of pairing, deformation and shell effects in the NME values.

Beta-beta decays and other rare processes

Neutrinoless double beta (0nbb) decay is a unique process because, if detected, it will imply the Majorana nature of neutrinos. Moreover, once an experimental lifetime will be measured, with the nuclear matrix elements (NMEs) very important information about the hierarchy an absolute masses of the neutrinos will be known. Therefore, a reliable calculation of the NMEs is crucial....
