| Publication Abstract: | The x-dependence of hadrons? generalized parton distributions (GPDs) F(x,?,t) is the most difficult to extract from the existing known processes, while the ? and t dependence are uniquely determined by the kinematics of the scattered hadron. We study the single diffractive hard exclusive processes for extracting GPDs in the photoproduction. We demonstrate quantitatively the enhanced sensitivity on extracting the x-dependence of various GPDs from the photoproduction cross sections, as well as the asymmetries constructed from photon polarization and hadron spin that could be measured at JLab Hall D by GlueX Collaboration and future facilities. |
