Generalized Parton Distributions of Pions. Spin Structure of Hadrons

Abstract

We present an extensive study on generalized parton distributions of pions. In particular, we present the results for the pion-photon transition distribution amplitudes in the Nambu - Jona-Lasinio model. We discuss the phenomenology of such objects and give explicit estimates for cross sections. The spin structure of the proton is also studied: we discuss the results for the T-odd transverse momentum distributions in quark models.
