Abstract: (WSP)

We show how a meson effective action, in which all of the meson parameters are finite, arises from a “global color symmetry” model involving a nonlocal current-current (four-quark) interaction. As an application of this general approach we present a covariant analysis of the ρ-π system and thus obtain estimates for the ρ meson mass and the coupling constant gρππ.
