Title of talk:	Deep Virtual Compton Scattering: from data to GPDs
Abstract:	Generalized Parton Distributions (GPDs) allow to describe the structure of the nucleon in a very rich and unprecedented way: they contain the correlations between the (transverse) position and (longitudinal) momentum distributions of the partons in the nucleon, they allow to derive the orbital momentum contribution of partons to the nucleon's spin, they provide an access to the nucleon's ($q\bar{q}$) content, etc... GPDs can be accessed experimentally through the exclusive leptoproduction of a photon (``Deep Virtual Compton Scattering", DVCS) -and possibly of a meson-. In this lecture, after an introduction to the formalism of GPDs, we will present the result of a recently developped fitter code which aims at extracting in a largely model-independent way the GPD information from experimental data. We will show the results of this code applied to the JLab and HERMES DVCS data, which begin to provide some new insights on nucleon structure.
