Meson Transition Form Factors From A QCD Model Field Theory

Abstract

We discuss form factors and coupling constants for the ${\gamma }^{\ast }{\pi }^0\gamma$, $\rho \pi \pi$ and $\gamma \pi \rho$ interactions generated by a model field theory that produces finite size $\bar{q}q$ meson modes. The approach implements dressing of the vertices and propagators consistent with dynamical chiral symmetry breaking, gauge invariance, quark confinement and perturbative QCD.
