Skewness-dependent moments of the pion GPD from nonlocal quark-bilinear correlators
Xiang Gao, Swagato Mukherjee, Qi Shi +2
We present lattice QCD calculations of the odd Mellin moments of pion valence-quark generalized parton distribution (GPD) up to fifth order, , and for the skewn…

Three-dimensional Imaging of Pion using Lattice QCD: Generalized Parton Distributions
Heng-Tong Ding, Xiang Gao, Swagato Mukherjee +4
In this work, we report a lattice calculation of -dependent valence pion generalized parton distributions (GPDs) at zero skewness with multiple values of the momentum transfer $…

QCD Predictions for Meson Electromagnetic Form Factors at High Momenta: Testing Factorization in Exclusive Processes
Heng-Tong Ding, Xiang Gao, Andrew D. Hanlon +6
We report the first lattice QCD computation of pion and kaon electromagnetic form factors, , at large momentum transfer up to 10 and 28 , respectively. Ut…
