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…
Realization of all-to-all fermion propagator for the first principle high accuracy strong interaction prediction
Zhi-Cheng Hu, Ji-Hao Wang, Xiangyu Jiang +4
We propose a ``blending" algorithm that projects the all-to-all fermion propagator onto spatial low-frequency modes (LFM) combined with a stochastic estimate of spatial high-freque…
Unveiling the Strong Interaction origin of Baryon Masses with Lattice QCD
Bolun Hu, Haiyang Du, Xiangyu Jiang +3
Both the Higgs mechanism and strong interactions contribute to the masses of visible matter, yet how the six Higgs-generated quark masses and uniform strong interaction strength de…
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…
