Unraveling nucleon structure through Deeply Virtual Compton Scattering Carlos Munoz Camacho CEA-Saclay (Gif-sur-Yvette, France) Quantitatively understanding quark and gluon confinement in Quantum Chromodynamics is one of the outstanding problems and compelling questions in physics today. In order to unravel hadron structure one needs to resort to experiments. The recently developed Generalized Parton Distributions (GPDs) provide a promising way to understand the mechanism which form hadrons from their underlying quark and gluonic degrees of freedom. Deeply Virtual Compton Scattering (DVCS) is the golden process to access GPDs experimentally. The first dedicated DVCS experiment ran in 2004 at Jefferson Lab and will be the main focus of this seminar. The high luminosity conditions presented a major challenge in terms of background rates. The setup and data acquisition system specifically developed for this experiment will be described, and the performances of detectors under running conditions discussed. The analysis and preliminary results on the single spin cross section difference will be presented. These are the first precise measurements of GPDs as a function of the momentum transfer to the proton and will provide strong constraints to GPD models and parametrizations.
