Generalized Parton Distributions from Hard Exclusive Compton-like and Vector meson production

Hard exclusive Compton-like process, involving the exchange of at least one high virtuality photon off a quark of the nucleon, or hard exclusive vector meson production (where a hard scale is provided by the exchange of a virtual photon or by the meson mass), enable access to the partonic structure of the nucleon, in particular it the transverse distribution versus the longitudinal momentum of the partons. The latter can be parametrized by the so-called Generalized Parton Distributions (GPDs). We propose a simulation framework to study these reactions and will present the interest of such studies for accessing GPDs, our methods and simulations, and our projections for potential future experiments.
