Abstract.

The CLAS and Hall A Collaborations at Jefferson Laboratory have recently released new results for the \( e p\rightarrow e p \gamma\) 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.
