Isovector parton distribution functions of the proton on a superfine lattice
Zhouyou Fan, Xiang Gao, Ruizi Li +7
We study isovector unpolarized and helicity parton distribution functions (PDF) of the proton within the framework of Large Momentum Effective Theory. We use a gauge ensemble, gene…
Machine-Learning Prediction for Quasi-PDF Matrix Elements
Rui Zhang, Zhouyou Fan, Ruizi Li +2
There have been rapid developments in the direct calculation in lattice QCD (LQCD) of the Bjorken- dependence of hadron structure through large-momentum effective theory (LaMET)…
Nucleon Transversity Distribution at the Physical Pion Mass from Lattice QCD
Yu-Sheng Liu, Jiunn-Wei Chen, Luchang Jin +5
We report a state-of-the-art lattice calculation of the isovector quark transversity distribution of the proton at the physical pion mass. Within the framework of large-momentum ef…
Proton Isovector Helicity Distribution on the Lattice at Physical Pion Mass
Huey-Wen Lin, Jiunn-Wei Chen, Xiangdong Ji +6
We present a state-of-the-art calculation of the isovector quark helicity Bjorken- distribution in the proton using lattice-QCD ensembles at the physical pion mass. We compute q…
