Effects of quark GPDs in meson electroproduction

Abstract

We analyze light meson electroproduction in the intermediate energy range where the quark contributions are essential. Our calculations are carried out on the basis of the handbag approach. We study cross sections and spin asymmetries for various vector and pseudoscalar mesons. Our results are in good agrement with COMPASS and HERMES experiments.
