Abstract
We shortly review the status of perturbative corrections to hard exclusive processes, which were partially obtained by utilizing conformal symmetry. We outline the conformal partial wave expansion of generalized parton distributions (GPDs) and hard exclusive amplitudes, which can be used for a model dependent extraction of the two-dimensional momentum fraction shape of GPDs by means of evolution. We exemplify this method and point out it importance for the description of collider data in the small x Bj region.
