Mass Relations ofSU3in a Solubleω−φMixing Model

A soluble model of $S{U}_3$-invariant meson-vecton interactions is investigated. $\omega -\phi$ mixing is introduced as a soluble, symmetry-breaking interaction. Small form-factor effects in this interaction are also treated. Mass renormalization is carried out to study higher order effects in the Gell-Mann-Okubo formula for mesons. Two new mass formulas for vectons and an equation relating vecton masses to meson masses is derived. Finally, relations between bare coupling constants are studied. The agreement with experiment is generally good.
