Generalized Parton Distributions and Deep Exclusive Reactions: Present   Program at JLab
  We review briefly the physical concept of generalized parton distributions and the experimental challenges associated with the corresponding measurements of deep exclusive reactions.The first data obtained at Jefferson Lab for exclusive photon (DVCS) and vector meson (DVMP) electroproduction above the resonance-excitation region are described . Two upcoming dedicated DVCS experiments are presented in some detail.
