Some Results on Vector and Tensor Meson Mixing in a Generalized QCD-like Theory

We present results for the mixing of quark flavor eigenstates to form low-lying vector and tensor meson mass eigenstates in a generalized QCD-like theory with $\ell$ massless or light, degenerate quarks and one quark of substantial mass, $m_Q$. We show that as $m_Q/Λ$ gets large, where $Λ$ is the confinement scale, the angle governing this mixing approaches $\arctan(1/\sqrt{\ell})$. We give a generalization of the Gell-Mann Okubo mass relation for this theory. A comparison of the $\ell=2$ results with data on $ω$-$ϕ$ and $f_2(1275)$-$f_2'(1525)$ mixing is included.
