Correlations Between Neutrinoless Double-Beta, Double Gamow-Teller and Double-Magnetic Decays in the pnQRPA Framework
We explore the relation between the nuclear matrix elements of neutrinoless double-beta (0 ) decay and two other processes: double Gamow-Teller (DGT) and double-magnetic-dipole ( 1 1) transitions, with focus on medium-mass to heavy nuclei studied with the proton-neutron quasiparticle random-...

| Sumario: | We explore the relation between the nuclear matrix elements of neutrinoless double-beta (0 ) decay and two other processes: double Gamow-Teller (DGT) and double-magnetic-dipole ( 1 1) transitions, with focus on medium-mass to heavy nuclei studied with the proton-neutron quasiparticle random-phase approximation ( QRPA) framework. We explore a wide span of isoscalar proton-neutron pairing strengths covering the typical range of values that describe well - and two-neutrino -decay data. Our results indicate good linear correlations between 0 and both DGT and 1 1 matrix elements. Together with future measurements of DGT and 1 1 transitions, these correlations could help constrain the values of the 0 -decay nuclear matrix elements. |
