Title:     Theory and Phenomenology of Exclusive Hadronic Proccesses

Abstract: Hard exclusive processes allow to resolve the internal structure of hadrons and even nuclei from a new perspective. The non-perturbative information about the partonic content, encoded in generalized parton distributions and distribution amplitudes, is complementary to those obtained from inclusive measurements. In this talk the theory for these processes is reviewed and
phenomenological applications are discussed. In particular, a new representation of generalized parton distributions and hadronic
amplitudes as Mellin--Barnes integral will be presented. This representation allows for a flexible parameterization of
generalized parton distributions, it can be used for a fast and stable numerical evaluation of observables, and is the key to
improve the theoretical framework beyond the next--to--leading order accuracy.

Stimulants available 15 minutes before the talk.
