Asymptotic Long-Distance Expansion of Euclidean Correlators in Lattice Parton Applications
Xiangdong Ji, Yizhuang Liu, Yushan Su
Bilinear Euclidean quark and gluon correlators with Wilson links have been used widely for applications of large-momentum effective field theories to computing non-perturbative col…

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…

Hybrid renormalization for distribution amplitude of a light baryon in large momentum effective theory
Haoyang Bai, Jun Hua, Xiangdong Ji +9
Lightcone distribution amplitudes for a light baryon can be extracted through the simulation of the quasi-distribution amplitudes (quasi-DAs) on the lattice. We implement the hybri…
