Towards unpolarized GPDs from pseudo-distributions
A bstract We present an exploration of the unpolarized isovector proton generalized parton distributions (GPDs) H u − d ( x , ξ , t ) and E u − d ( x , ξ , t ) in the pseudo-distribution formalism using distillation. Taking advantage of the large kinematic coverage made possible by this approach, we present results on the moments of GPDs up to the order x 3 — including their skewness dependence — at a pion mass m π = 358 MeV and a lattice spacing a = 0 . 094 fm.
