Generalized parton distributions of few body systems

Abstract

The relevance of measuring Generalized Parton Distributions (GPDs) for few nucleon systems is illustrated. An approach which permits to calculate the GPDs of hadrons made of composite constituents by proper convolutions is described. The application of the method to the nucleon target, assumed to be made of composite constituents is reviewed. Calculations of GPDs for few nucleon systems are summarized, with special emphasis to the $^3$He target.Comment: 4 pages, 2 figures, talk given at the "18th International IUPAP Conference on Few-Body Problems in Physics" Santos, Sao Paulo, Brazil, August 21-26, 200
