Description

The structure of the pion is studied within a dynamical model of the Bethe-Salpeter amplitude with dressed gluon exchange and constituent quarks [1]. The model reproduces the pion charge form-factor [2] and also provides the valence quark PDF, which is also compared to existing models and experimentally extracted PDF's [3]. Also results for some of the transverse momentum distributions will be shown [4].
