Pion Transition Form Factor in Lattice QCD
Shihao Su, Liuming Liu, Peng Sun
The paper computes the neutral pion transition form factor in lattice QCD, using a blending method for all-to-all propagators and distillation for pion states, and finds that disco…
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…
Accurate B meson and Bottomonium masses and decay constants from the tadpole improved clover ensembles
Mengchu Cai, Hai-Yang Du, Xiangyu Jiang +4
We present a determination of the bottom quark mass, the masses of S-wave bottom mesons, and their decay constants using an anisotropic clover fermion discretization for the heavy…
Precision determination of nucleon iso-vector scalar and tensor charges at the physical point
Ji-Hao Wang, Zhi-Cheng Hu, Xiangdong Ji +4
We report a high precision calculation of the isospin vector charge of the nucleon using recently proposed ``blending" method which provides a high-precision stochastic e…
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…
Unpolarized gluon PDF of the nucleon from lattice QCD at physical point in the continuum limit
Chen Chen, Hongxin Dong, Liuming Liu +8
We report a state-of-the-art lattice QCD calculation of the nucleon unpolarized gluon parton distribution function employing large-momentum effective theory. The calculation is car…
