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 Study of Pion Electroproduction and Weak Production from a Nucleon
Yu-Sheng Gao, Zhao-Long Zhang, Xu Feng +3
Quantum fluctuations in QCD influence nucleon structure and interactions, with pion production serving as a key probe of chiral dynamics. In this study, we present a lattice QCD ca…
Lattice calculation of the and s-wave scattering length
Yu Meng, Chuan Liu, Xin-Yu Tuo +2
We calculate the s-wave scattering length in the sector of and the sector of using three twisted mass gauge ensembles with the lattice spacing…
Nucleon electric polarizabilities and nucleon-pion scattering at physical pion mass
Xuan-He Wang, Zhao-Long Zhang, Xiong-Hui Cao +5
We present a lattice QCD calculation of the nucleon electric polarizabilities at the physical pion mass. Our findings reveal the substantial contributions of the states to the…
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…
