Description
The detection of the neutrinoless double-decay is nowadays one of the main
goals in many laboratories all around the world, triggered by the search
of ”new physics” beyond the Standard Model.
I report on the calculation of the nuclear double-beta decay properties for
nuclei that are possible candidates for such a process within the
framework of the realistic shell model.
The effective shell-model Hamiltonian and transition operators are derived
by way of many-body perturbation theory without resorting to empirical
effective quenching factors for the transition operators. The
computational challenges of such an approach will be underlined.
The reported research activity is carried in the frame of the STRENGTH
(STructure and REaction Nuclei: towards a Global THeory) project of INFN.
