摘要：

Working at twist 2 accuracy and assuming the dominance of the Generalized Parton Distribution H we study the helicity-dependent and independent cross sections measured in Hall A and the beam spin asymmetries measured in Hall B at Jefferson Laboratory. We extract the real and imaginary parts of the Compton Form Factor H, the latter being obtained with a 20-50 % uncertainty. We discuss our results and compare to other extractions as well as to the popular VGG model. We pay extra attention to the estimation of systematic errors on the extraction of H.
