Total Gluon Helicity Contribution to the Proton Spin from Lattice QCD
Dian-Jun Zhao, Long Chen, Hongxin Dong +8
We report a state-of-the-art lattice QCD calculation of the total gluon helicity contribution to the proton spin, . The calculation is done on ensembles with three different la…

Comparison of the mixed-fermion-action Effects using different fermion and gauge actions with 2+1 and 2+1+1 flavors
Zun-Xian Zhang, Mengchu Cai, Bolun Hu +4
The leading-order low-energy constant in mixed-action chiral perturbation theory is calculated using -flavor gauge ensembles with HISQ fermions and a tadpole-i…

Low energy constant and mixed-action effect
Dian-Jun Zhao, Yi-Bo Yang
We present the pion mass and decay constant using the overlap fermion valence on domain wall (DW) fermion sea at several lattice spacings. The mixed action effect in the lattice ca…
