Description
Some Hard exclusive processes off thenucleon, involving the exchange of at least one high virtualityphoton off a quark, enable access to the transverse partonic structureversus the longitudinal momentum of the partons. The so-called Generalized Parton Distributions (GPDs), parametrizing theseprocesses, contain this information. Their interpretation can lead totomographic views of the partonic structure, a new way to access thespin repartitions and correlations among the partonic constituents...Jefferson Lab Hall A and C have been very successful over the lastcouple of years in measuring reactions, such as DVCS, enabling the extraction of GPDs and constraining GPD models. In this talk, we willdiscuss past results from JLab and what we learned out of them, aswell near future experiments, including new measurements, such as Timelike Compton Scattering, Hard Exclusive Meson Production, andpotential projects, such as Double Deeply Virtual Compton Scattering. We will discuss how the JLab Hall A/C GPD program is broadening the perspectives in GPD's related research in the valence quark region.
