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…

Renormalons and power corrections in pseudo- and quasi-GPDs
Vladimir Braun, Maria Koller, Jakob Schoenleber
High-order behavior of the perturbative expansion for short-distance observables in QCD is intimately related to the contributions of small momenta in the corresponding Feynman dia…
