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…
radiative corrections with lattice input
Chien-Yeah Seng
We will describe several pioneering efforts in the study of electromagnetic radiative corrections to semileptonic decay processes, with particular emphasis on the role of lattice Q…
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…
