Correlations Between Neutrinoless Double-Beta, Double Gamow-Teller and Double-Magnetic Decays in the pnQRPA Framework

# metadata.dc.description.abstract[].value
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.
