Description

Deeply Virtual Compton Scattering (DVCS) is the easiest reaction that probes the Generalized Parton Distributions (GPDs) of the nucleon. GPDs offer the exciting possibility of mapping the 3-D internal structure of protons and neutrons by providing a transverse image of the constituents as a function of their longitudinal momentum. An extensive experimental program is currently pursued at Jefferson Lab to access GPDs through DVCS. New results from Hall A and Hall B recently released will be shown and discussed. Special attention will be devoted to the applicability of the GPD formalism at the moderate values of momentum transfer (Q2) available at Jefferson Lab, and the necessity of higher twist corrections in order to fully describe the extremely precise data from these dedicated high luminosity experiments. An outlook of additional DVCS experiments under analysis and planned with the future Upgrade of Jefferson Lab to 11 GeV will be also presented.
