Impact of Dynamical Charm Quark and Mixed Action Effect on Light Hadron Masses and Decay Constants
Tong-Wei Lin, Zun-Xian Zhang, Mengchu Cai +8
We investigate the impact of including a dynamical charm quark on the properties of light hadrons. Our study compares the calculations performed on 2+1+1 flavor (HISQ fermion) ense…
Toward precise gauge fixing for the lattice QCD
Li-Jun Zhou, Dian-Jun Zhao, Wei-jie Fu +3
Lattice QCD provides a first-principles framework for solving Quantum Chromodynamics (QCD). However, its application to off-shell partons has been largely restricted to the Landau…
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-…
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 l…
Charmed meson masses and decay constants in the continuum from the tadpole improved clover ensembles
Hai-Yang Du, Bolun Hu, Mengchu Cai +10
We present the determination of the charm quark mass, the masses, and decay constants of charmed mesons using thirteen 2+1 flavor gauge ensembles at five different lattice spacings…
