Title: Generalized parton distributions from deep virtual compton scattering at CLAS

Here, we have analyzed the beam spin asymmetry and the longitudinally polarized target spin asymmetry of the Deep Virtual Compton Scattering process, recently measured by the Jefferson Lab CLAS collaboration. Our aim is to extract information about the Generalized Parton Distributions of the proton. By fitting these data, in a largely model-independent procedure, we are able to extract numerical values for the two Compton Form Factors $$H_{Im}$$ and $$\tilde{H}_{Im}$$ with uncertainties, in average, of the order of 30%.
