First-Principles Determination of the QCD Contribution to the Axion-Photon Coupling Using Domain-Wall Fermions
Tian Lin, Hao-Yang Cheng, Xu Feng +3
The axion-photon coupling, crucial for experimental axion searches and tests of the strong CP solution, receives a substantial model-independent contribution …
First-principles determination of anomaly-induced pion decay beyond the chiral limit
Tian Lin, Xu Feng, Lu-Chang Jin +2
The two-photon decay of the neutral pion is fixed in the chiral limit by the Adler-Bell-Jackiw anomaly, while nonzero quark masses induce few-percent corrections that must be deter…
First-Principles Determination of the Proton-Proton Fusion Matrix Element from Lattice QCD
Zi-Yu Wang, Xu Feng, Bo-Hao Jian +2
Proton-proton fusion is the fundamental weak reaction initiating stellar energy production, and a first-principles determination of its matrix element remains a long-standing goal…
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 QCD calculation of the -pole contribution to the hadronic light-by-light scattering in the anomalous magnetic moment of the muon
Tian Lin, Mattia Bruno, Xu Feng +4
We develop a method to compute the pion transition form factor directly at arbitrary space-like photon momenta and use it to determine the -pole contribution to the hadronic l…
Lattice QCD calculation of the subtraction function in forward Compton amplitude
Yang Fu, Xu Feng, Lu-Chang Jin +2
The subtraction function plays a pivotal role in calculations involving the forward Compton amplitude, which is crucial for predicting the Lamb shift in muonic atom, as well as the…
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…
