Gluon Unpolarized, Polarized, and Transversity GPDs from Lattice QCD: Lorentz-Covariant Parametrization (Part I)
Jakob Schoenleber, Raza Sabbir Sufian, Taku Izubuchi +1
We identify the matrix elements necessary to determine the leading-twist gluon generalized parton distributions (GPDs) $H_g,~E_g,~\wt{H}_g,~\wt{E}_g,~H^T_g,~E^T_g, \wt{H}^T_g ,~\wt…

Polarized and unpolarized gluon PDFs: generative machine learning applications for lattice QCD matrix elements at short distance and large momentum
Talal Ahmed Chowdhury, Taku Izubuchi, Methun Kamruzzaman +6
Lattice quantum chromodynamics (QCD) calculations share a defining challenge by requiring a small finite range of spatial separation between quark/gluon bilinears for controlla…
