The inverse process of ${}^{9}\mathrm{Be}$ photo-disintegration, including both sequential and direct reactions combining two $\alpha$ and a neutron into $^9\textrm{Be}$, is a reaction of astrophysical interest, because it represents an alternative path to the ${}^{12}\mathrm{C}$ formation in a neutron-rich environment. Here we present the study of the inclusive reaction $\gamma +...

We study dark matter scattering off ${}^2$H and ${}^4$He nuclei, assuming DM to be composed by weak interacting massive particles, WIMPs. In order to parametrize the WIMP-nucleon interaction the chiral effective field theory ($\chi$EFT) approach is used. Considering only interactions invariant under parity, charge conjugation and time reversal, we examine five interaction types: scalar,...

34. Recent Developments in $\beta$ decay studies within the Nuclear Shell Model

Giovanni De Gregorio (Istituto Nazionale di Fisica Nucleare)

The necessity of calculating reliable nuclear matrix elements for neutrinoless double $\beta$ decay has further stimulated the research on the mechanisms responsible for the renormalization of the $\beta$-decay operator. We tackle this point using the many-body perturbation theory to derive effective Hamiltonian and operators for nuclear shell model calculations. Here, I will present recent...
