Superallowed Fermi transitions in RPA with a relativistic point-coupling energy functional

The self-consistent random phase approximation （RPA） approach with the residual interaction derived from a relativistic pointcoupling energy functional is applied to evaluate the isospin symmetry-breaking corrections δ c for the 0＋ → 0＋ superallowed Fermi transitions.With these δ c values,together w...

Description
Summary:The self-consistent random phase approximation （RPA） approach with the residual interaction derived from a relativistic pointcoupling energy functional is applied to evaluate the isospin symmetry-breaking corrections δ c for the 0＋ → 0＋ superallowed Fermi transitions.With these δ c values,together with the available experimental f t values and the improved radiative corrections,the unitarity of the Cabibbo-Kobayashi-Maskawa （CKM） matrix is examined.Even with the consideration of uncertainty,the sum of squared top-row elements has been shown to deviate from the unitarity condition by 0.1% for all the employed relativistic energy functionals.
