Lattice QCD Calculation of Electroweak Box Contributions to Superallowed Nuclear and Neutron Beta Decays

Peng-Xiang Ma, Xu Feng, Mikhail Gorchtein +5

We present the first lattice QCD calculation of the universal axial $γ W$ -box contribution $□_{γ W}^{V A}$ to both superallowed nuclear and neutron beta decays. This contributio…
