A Hybrid Renormalization Scheme for Quasi Light-Front Correlations in Large-Momentum Effective Theory
Xiangdong Ji, Yizhuang Liu, Andreas Schäfer +4
In large-momentum effective theory (LaMET), calculating parton physics starts from calculating coordinate-space- correlation functions in a hadron of moment…

Accessing gluon parton distributions in large momentum effective theory
Jian-Hui Zhang, Xiangdong Ji, Andreas Schäfer +2
Gluon parton distribution functions (PDFs) in the proton can be calculated directly on Euclidean lattices using large momentum effective theory (LaMET). To realize this goal, one h…

Unpolarized isovector quark distribution function from Lattice QCD: A systematic analysis of renormalization and matching
Yu-Sheng Liu, Jiunn-Wei Chen, Yi-Kai Huo +10
We present a detailed Lattice QCD study of the unpolarized isovector quark Parton Distribution Function (PDF) using large-momentum effective theory framework. We choose a quasi-PDF…
