The Generalized Parton Distribution program after the Jefferson Lab 12 GeV upgrade

The Generalized Parton Distribution framework was introduced in the late 90's and describes the nucleon in a revolutionary way, correlating the information from both momentum and transverse position space into experimentally accessible functions. After a brief introduction, this article reviews the Jefferson Lab 6 GeV measurements of Deeply Virtual Compton Scattering in Halls A and B, which give a unique access to Generalized Parton Distributions (GPD). The second half of this article reviews the Jefferson Lab 12 GeV upgrade in general terms, and then focuses on the GPD program in Halls A and B. This second generation of experiments will yield more accurate, more complete data in a wider kinematical range than any experiment ever before, using the full capability of a higher beam energy, higher luminosities, upgraded detectors and refined extraction techniques.
