# Generalized parton distributions

@article{Diehl2003GeneralizedPD, title={Generalized parton distributions}, author={M. Diehl}, journal={Physics Reports}, year={2003}, volume={388}, pages={41-277} }

We give an overview of the theory for generalized parton distributions. Topics covered are their general properties and physical interpretation, the possibility to explore the three-dimensional structure of hadrons at parton level, their potential to unravel the spin structure of the nucleon, their role in small-x physics, and efforts to model their dynamics. We review our understanding of the reactions where generalized parton distributions occur, to leading power accuracy and beyond, and… Expand
