Impact of chirality imbalance and nonlocal interactions on the QCD biased axionic domainwall interpretation of NANOGrav 15 year data
Ruotong Zhao, Zhao Zhang
We investigate the influence of the chirality imbalance with local CP-breaking in hot QCD on the generation of a stochastic gravitational wave background (SGWB) sourced by the axio…
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 test…
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 spa…
