Description
Evolution equations which control the scale dependence of generalized parton distributions (GPDs) are a crucial tool to extract accurately these objects from experimental data. They determine the propagation of uncertainty in the deconvolution problem of factorized observables, and offer a great opportunity to model GPDs in the small Bjorken-x limit. We use the recent momentum-space evolution code APFEL++ interfaced in the PARTONS framework to present results on the uncertainty of the extraction of GPDs, graviational form factors and the extrapolation of GPDs to vanishing skewness, an important aspect of the 3D-tomography program.
