Hard Meson Electroproduction And Twist-3 Effects

preprint2012arXivOpen access

Abstract

We analyze light meson electroproduction within the handbag model. We study cross sections and spin asymmetries for various mesons. The essential role of the transversity H~T\tilde H_T and E~T\tilde E_T GPDs in electroproduction of pseudoscalar mesons is found. Our results are in good agrement with experiment.
