Abstract

The mass splitting between the I = 0 ω meson and the I = 1 ρ mesons due to the ππ intermediate state self-energy process accessible to the ρ meson is calculated in a QCD based model of the strong interaction. The calculation is completely self-regularizing with every physical meson quantity used calculable and completely determined by the parameters in the microscopic quark action. The ππ loop integral is convergent with no renormalization necessary. Values for the mass splitting are obtained which are comparable with experiment.
