Computability of GPDs near in Lattice QCD
Yushan Su, Xiangdong Ji, Yizhuang Liu +1
In lattice QCD computations of generalized parton distributions (GPDs), the large momentum expansion generally requires all hard scales, and , to be muc…
Baryon Light-Cone Distribution Amplitudes from Lattice QCD: Formalism, Renormalization, Extrapolation, and Matching
Mu-Hua Zhang, Haoyang Bai, Min-Huan Chu +11
Baryon light-cone distribution amplitudes (LCDAs) are inherently multidimensional objects parametrized by two independent longitudinal momentum fractions, making their first-princi…

Euclidean Effective Theory for Partons in the Spirit of Steven Weinberg
Xiangdong Ji
The standard formulation of parton physics involves light-cone correlations of quark and gluon fields in a hadron, which leads to a widespread impression that it can only be studie…
