Description

I'll report on the calculation of the nuclear matrix element for the neutrinoless double-β decay process using the realistic shell model.
In this approach, we start from a realistic nucleon-nucleon potential and then derive the effective shell-model Hamiltonian and 0νββ decay operator within the many-body perturbation theory.
I'll focus my attention on a few candidates for the 0νββ decay detection, in a mass interval ranging from A = 76 up to A = 136.
To validate the reliability of the approach, the calculated spectroscopic properties and spin- and spin-isospin-dependent decay properties of the nuclei under investigation will be compared with the available experimental data.
