Description
Gamow–Teller resonance and double-beta decay of 48Ca are studied within TDA and STDA using realistic chiral interactions. A consistent description of the resonance is achieved, and isospin symmetry is restored. Two-particle–two-hole correlations are shown to impact nuclear matrix elements and contribute to the quenching of gA.
