Generalized Parton Distributions and Nucleon Resonances

We discuss the relations between Generalized Parton Distributions (GPDs) and nucleon resonances. We first briefly introduce the concept of “transition” GPDs. Then we discuss a straightforward application to the modelization of the N-$\mathrm{\Delta }$ magnetic transition form factor. Finally, we discuss the experimental aspects of the subject and present first preliminary experimental investigations in this field.
