Towards unpolarized GPDs from pseudo-distributions
摘要
We present an exploration of the unpolarized isovector proton generalized parton distributions (GPDs) Hu−d(x, ξ, t) and Eu−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 — including their skewness dependence — at a pion mass mπ = 358 MeV and a lattice spacing a = 0.094 fm.
