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.13 p.application/pdfeng(c) American Physical Society, 2023NeutrinsElectromagnetismeFísica nuclearNeutrinosElectromagnetismNuclear physicsCorrelations Between Neutrinoless Double-Beta, Double Gamow-Teller and Double-Magnetic Decays in the pnQRPA Frameworkinfo:eu-repo/semantics/article7464142024-10-15info:eu-repo/semantics/openAccess
