Abstract
Jefferson Laboratory with the current 12 GeV upgrade and a major program focused on the Generalized Parton Distributions has the opportunity to explore the Doubly Virtual Compton Scattering (DDVCS) process which would allow to probe GPDs surface for skewness different from the generalized bjorken variable.
Such an experiment requires high luminosity because of a cross section about 100 times smaller than regular Deeply Virtual Compton Scattering. Two letter of intent were submitted to the PAC to carry out this kind of measurement. One in a modified CLAS12 setup in Hall B with a luminosity of $10^{37} \cdot cm^{2}\cdot s^{-1}$ and another one using the Solenoidal Large Intensity Device (SoLID) is a solenoidal detector equipped with Gas Electron Multiplier trackers, calorimetry and Cerenkov detectors design to run with luminosity as high as a couple of $10^{38} \cdot cm^{2}\cdot s^{-1}$.
