Abstract: (Springer)
We present an exploration of the unpolarized isovector proton generalized parton distributions (GPDs) Hud^{u−d}(x, ξ, t) and Eud^{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 x3^{3} — including their skewness dependence — at a pion mass mπ_{π} = 358 MeV and a lattice spacing a = 0.094 fm.
