Analysis of Deeply Virtual Compton Scattering Data at Jefferson Lab and Proton Tomography

Understand

The CLAS and Hall A collaborations at Jefferson Laboratory have recently released new results for the ep->ep{\gamma} reaction.

• We analyze these new data within the Generalized Parton Distribution formalism.
• Employing a fitter algorithm introduced and used in earlier works, we are able to extract from these data new constraints on the kinematical dependence of three Compton Form Factors.
• Based on experimental data, we subsequently extract the dependence of the proton charge radius on the quarks longitudinal momentum fraction.
