Analysis of the Intermediate-State Contributions to Neutrinoless Double β− Decays
A comprehensive analysis of the structure of the nuclear matrix elements (NMEs) of neutrinoless double beta-minus (0νβ-β-) decays to the 0+ ground and first excited states is performed in terms of the contributing multipole states in the intermediate nuclei of 0νβ-β- transitions. We concentrate on t...

| description | A comprehensive analysis of the structure of the nuclear matrix elements (NMEs) of neutrinoless double beta-minus (0νβ-β-) decays to the 0+ ground and first excited states is performed in terms of the contributing multipole states in the intermediate nuclei of 0νβ-β- transitions. We concentrate on the transitions mediated by the light (l-NMEs) Majorana neutrinos. As nuclear model we use the proton-neutron quasiparticle random-phase approximation (pnQRPA) with a realistic two-nucleon interaction based on the Bonn one-boson-exchange G matrix. In the computations we include the appropriate short-range correlations, nucleon form factors, and higher-order nucleonic weak currents and restore the isospin symmetry by the isoscalar-isovector decomposition of the particle-particle proton-neutron interaction parameter gpp. |
