Vector Meson Dominance and Free Quarks

Abstract

We study the electromagnetic pion form factor and the VV - AA two point function for momenta -(600 MeV)^2 < q^2 < (600 MeV)^2 and we note the similarity between vector meson dominance and two versions of the free constituent quark model. The similarity is more striking when the momentum dependence of the quark mass is taken into account. We consider the implications for QCD and other theories.
