Hard Meson Electroproduction And Twist-3 Effects [PDF]
S. V. GoloskokovWe analyze light meson electroproduction within the handbag model. We study cross sections and spin asymmetries for various mesons. The essential role of the transversity $\tilde H_T$ and $\tilde E_T$ GPDs in electroproduction of pseudoscalar mesons is found. Our results are in good agrement with experiment.View original: http://arxiv.org/abs/1112.2813
