Cross sections for the exclusive photon electroproduction on the proton and Generalized Parton Distributions
Abstract
Unpolarized and beam-polarized four-fold cross sections $$\frac{d^4 \sigma}{dQ^2 dx_B dt d\phi}$$ for the $$ep\to e^\prime p^\prime \gamma$$ reaction were measured using the CLAS detector and the 5.75-GeV polarized electron beam of the Jefferson Lab accelerator, for 110 ($$Q^2,x_B,t$$) bins over the widest phase space ever explored in the valence-quark region. Several models of Generalized Parton Distributions (GPDs) describe the data well at most of our kinematics. This increases our confidence that we understand the GPD $$H$$, expected to be the dominant contributor to these observables. Thus, through a leading-twist extraction of Compton Form Factors, these results reveal a tomographic image of the nucleon.
