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…
Unpolarized gluon PDF of the nucleon from lattice QCD at physical point in the continuum limit
Chen Chen, Chunhua Zeng, Hongxin Dong +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…
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) combines the projection with a stochastic estimate of spat…
Quark Transverse Spin-Momentum Correlation of the Nucleon from Lattice QCD: The Boer-Mulders Function
Lingquan Ma, Jun Hua, Andreas Schäfer +9
We present the first lattice QCD calculation of the quark transverse spin-momentum correlation, i.e., the naive time-reversal-odd Boer-Mulders function, of the nucleon, using large…
