| contents | 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. |
