Inside Mesons: Coupling Constants and Form Factors

We illustrate the progress of covariant QCD phenomenology for the description of meson coupling constants and form factors. As examples, we discuss the $\rho\pi\pi$ and $\gamma \pi\rho$ interactions, the $\rho$ contribution to the pion charge radius, and the $\rho NN$ and $\omega NN$ vector and tensor coupling constants and form factors.
