Nonlocal effective field theory and its applications
P. Wang, Zhengyang Gao, Fangcheng He +3
We review recent applications of nonlocal effective field theory, focusing in particular on nonlocal chiral effective theory and nonlocal quantum electrodynamics (QED), as well as…
Nonlocal chiral contributions to generalized parton distributions of the proton at nonzero skewness
Zhengyang Gao, Fangcheng He, Chueng-Ryong Ji +3
We compute the one-loop contributions to spin-averaged generalized parton distributions (GPDs) in the proton from pseudoscalar mesons with intermediate octet and decuplet baryon st…
RI/(S)MOM renormalizations of overlap quark bilinears with different levels of hypercubic smearing
Yujiang Bi, Ying Chen, Ming Gong +5
On configurations with 2+1-flavor dynamical domain-wall fermions, we calculate the RI/(S)MOM renormalization constants (RC) of overlap quark bilinears. Hypercubic (HYP) smearing is…
Distance between various discretized fermion actions
Dian-Jun Zhao, Gen Wang, Fangcheng He +4
We present the leading order mixed-action effect using HISQ, clover or overlap valence fermion acti…
Nucleon form factors and parton distributions in nonlocal chiral effective theory
P. Wang, Fangcheng He, Chueng-Ryong Ji +1
We present a review of recent applications of nonlocal chiral effective theory to hadron structure studies. Starting from a nonlocal meson--baryon effective chiral Lagrangian, we s…
RI/MOM and RI/SMOM renormalization of quark bilinear operators using overlap fermions
Fangcheng He, Yu-Jiang Bi, Terrence Draper +3
We present the vector, scalar and tensor renormalization constants (RCs) using overlap fermions with either regularization independent momentum subtraction (RI/MOM) or symmetric mo…

Fangcheng He, Chueng-Ryong Ji, W. Melnitchouk +2
We calculate the spin-averaged generalized parton distributions (GPDs) of sea quarks in the proton at zero skewness from nonlocal covariant chiral effective theory, including one-l…

Jun Hua, Min-Huan Chu, Jin-Chen He +10
We present the state-of-the-art lattice QCD calculation of the pion and kaon light-cone distribution amplitudes (DAs) using large-momentum effective theory. The calculation is done…
Renormalization constants of overlap quark bilinear operators from RI/MOM and RI/SMOM scheme
Fangcheng He, Yi-Bo Yang
We calculate the renormalization constants (RCs) of vector, axial, vector scalar, pseudoscalar and tensor quark operators of the overlap valence fermion, on the 11 gauge ensembles…
Chiral extrapolation of the charged-pion magnetic polarizability with Padé approximant
Fangcheng He, D. B. Leinweber, A. W. Thomas +1
The background magnetic-field formalism of Lattice QCD has been used recently to calculate the magnetic polarizability of the charged pion. These numerical simulation…
A Demonstration of Hadron Mass Origin from QCD Trace Anomaly
Fangcheng He, Peng Sun, Yi-Bo Yang
Quantum chromodynamics (QCD) claims that the major source of the nucleon invariant mass is not the Higgs mechanism but the trace anomaly in QCD energy momentum tensor. Although exp…

Fangcheng He, D. B. Leinweber, A. W. Thomas +1
The magnetic polarizability of the neutral pion has been calculated in the background magnetic-field formalism of Lattice QCD. In this investigation, the chiral extrapolation of th…

Fangcheng He, P. Wang
We propose a mechanism for the Sivers distribution function in proton with chiral Lagrangian. By introducing the gauge link of the vector meson, the transverse momentum dependent d…
