TLDR
In this article, the nuclear wave functions for the required initial and final nuclear states are derived by employing the proton-neutron (p-n) quasi-particle random phase approximation (QRPA) which has been previously tested in our neutral-current v-nucleus studies for Te isotopes.Abstract:
Neutrino-nucleus reactions, involving both neutral current (NC) and charged current (CC) interactions are important probes in modern neutrino physics searches. In the present work, we study the concrete CC reactions 130 Te(vl,l−)130 I and 130 Te(l,l+)130Sb which are of current experimental interest for the CUORE and COBRA experiments operating at Gran Sasso underground laboratory in Italy. The nuclear wave functions for the required initial and final nuclear states are derived by employing the proton-neutron (p-n) quasi-particle random phase approximation (QRPA) which has been previously tested in our neutral-current v-nucleus studies for Te isotopes.read more

A unified formalism for the basic nuclear matrix elements in semi-leptonic processes

TL;DR: In this paper, a general compact formalism, appropriate for the description of transition amplitudes in semi-leptonic processes involving lepton-nucleus interactions, is presented, and closed analytic expressions for the reduced matrix elements of all the basic tensor operators originating from a multipole expansion of the relevant hadronic current density and the use of harmonic oscillator basis are derived.
