Description

I will present how perturbative evolution offers in theory the possibility of a model independent extraction of generalized parton distributions (GPDs) from exclusive processes such as deeply virtual Compton scattering (DVCS), but falls short of its promises practically at moderate skewness -- a problem illustrated through the concept of shadow GPDs. However, perturbative evolution provides crucial insights to the modeling of GPDs at small x. I will open up on the perspectives provided by non-perturbative evolution computed in lattice QCD.
