Generalized Parton Distributions of Pions. Spin Structure of Hadrons

Understand

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.
