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…
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…
