    • Abstract


      Two-neutrino $\beta \beta$ decay matrix elements and half-life of 48Ca are calculated after including neutron–proton pairing correlations in projected Hartree–Fock–Bogoliubov (PHFB) formalism. The GT matrix elements in $2\nu \beta \beta$ decay are reduced due to broader smearing of Fermi surfaces. Half-life results for $2\nu \beta \beta$ decay of 48Ca with np pairing are better than without pairing.
