What can we lean about GPDs from light meson leptoproduction experiments
  On the basis of the handbag approach we study cross sections and spin asymmetries for leptoproduction of various vector and pseudoscalar mesons. Our results are in good agrement with high energy experiments. We analyse what information about Generalized Parton Distributions (GPDs) can be obtained from these reactions.
