Pion Transition Form Factor in Lattice QCD
Shihao Su, Liuming Liu, Peng Sun
We investigate the neutral pion transition form factor in lattice QCD and confirm that the connected and disconnected contributions have the same…
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…
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…
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…
