Neutrinoless double beta decay within Self-consistent Renormalized Quasiparticle Random Phase Approximation and inclusion of induced nucleon currents
The first, to our knowledge, calculation of neutrinoless double beta decay (0νββ-decay ) matrix elements within the self-consistent renormalized Quasiparticle Random Phase Approximation (SRQRPA) is presented. The contribution from the momentum-dependent induced nucleon currents to 0νββdecay amplitude is taken into account. A detailed nuclear structure study includes the discussion of the sensit...

متن کاملGeneral behavior of double beta decay amplitudes in the quasiparticle random phase approximation.
Simple formulae for the 0+ → 0+ double beta decay matrix elements, as a function of the particle-particle strength gpp, have been designed within the quasiparticle random phase approximation. The 2ν amplitude is a bilinear function of gpp, and all 0ν moments behave as ratios of a linear function and the square root of another linear function of gpp. It is suggested that these results are of gen...
متن کاملNeutrinoless double beta decay
The status of the search for neutrinoless double beta decay is reviewed. The effort to reach the sensitivity needed to cover the effective Majorana neutrino mass corresponding to the degenerate and inverted mass hierarchy is described. Various issues concerning the theory (and phenomenology) of the relation between the 0νββ decay rate and the absolute neutrino mass scale are discussed, in parti...
