Abstract:
We report the first ab initio calculation of the nuclear-structure-dependent radiative correction δ_{NS} to the ^{10}C→^{10}B superallowed transition, computed with the no-core shell model and chiral effective field theory. We obtain δ_{NS}=-0.422(29)_{nuc}(12)_{n,el} with a 1.6-times reduction in the total uncertainty when compared to the current literature estimate based on the shell model and Fermi gas picture. This Letter paves the way for a precise determination of V_{ud} from superallowed beta decays within a systematically improvable framework.
