Hard gluon evolution of nucleon generalized parton distributions in the light-front quark model

Abstract

We incorporate the perturbative evolution effects in the generalized parton distributions (GPDs) calculated in effective light-front quark model for the nucleon. The perturbative effects enter into formalism through the evolution of GPDs according to the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-like (DGLAP) equation. We obtain the evolved GPDs in the momentum space and transverse impact parameter space. We observe that combining the light-front quark model with the perturbative evolution effects, give the effective model for studying the phenomenological GPDs.
