Lattice QCD determination of the box contribution to the proton weak charge

Zhao-long Zhang, Xu Feng, Mikhail Gorchtein +3

We present the first lattice QCD determination of the box contribution to parity-violating electron-proton scattering, , a key ingredient for the precise tests…

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 -box contribution to both superallowed nuclear and neutron beta decays. This contributio…

Lattice QCD calculation of the electroweak box diagrams for the kaon semileptonic decays

Peng-Xiang Ma, Xu Feng, Mikhail Gorchtein +2

We present a lattice QCD calculation of the axial -box diagrams relevant for the kaon semileptonic decays. We utilize a recently proposed method, which connects the electroweak…

Extracting the low-energy constant at three flavors from pion-kaon scattering

Chaitra Kalmahalli Guruswamy, Ulf-G. Meißner, Chien-Yeah Seng

Based on our analysis of the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude, we provide the first determination of the…

New method for calculating electromagnetic effects in semileptonic beta-decays of mesons

Chien-Yeah Seng, Xu Feng, Mikhail Gorchtein +2

We construct several classes of hadronic matrix elements and relate them to the low-energy constants in Chiral Perturbation Theory that describe the electromagnetic effects in the…
