Generelized Parton Distributions in light meson production

Abstract

We analyze light meson electroproduction within the handbag model, where the amplitude factorizes into Generelized Parton Distributions (GPDs) and a hard scattering part. The cross sections and spin asymmetries for various vector and pseudoscalar mesons are analyzed. We discuss what information on hadron structure can be obtained from GPDs.Comment: Latex, 14 pages, 12 figures, Presented at the 5th joint International HADRON STRUCTURE '11 Conference, June 27- July 1, 2011, Tatranska Strba (Slovak Republic
