Generalized parton distributions of the pion in a Bethe-Salpeter approach

Generalized parton distribution functions (GPDs) are calculated in a field theoretic formalism using a covariant Bethe-Salpeter approach for the determination of the bound-state wave function. The procedure is first described in an exact calculation in scalar Electrodynamics, and then extended to the Nambu-Jona-Lasinio model, a realistic theory of the pion. In both cases we demonstrate that all important features required by general physical considerations, like symmetry properties, sum rules and the polynomiality condition, are explicitly verified.
