- A bstract We study q ¯ q -hybrid mixing for the light vector mesons and q ¯ q -glueball mixing for the light scalar mesons in Monte-Carlo based QCD Laplace sum rules. By calculating the two-point correlation function of a vector q ¯ γ μ q (scalar q ¯ q ) current and a hybrid (glue- ball) current we are able to estimate the mass and the decay constants of the corresponding mixed “physical state” that couples to both currents. Our results do not support strong quark/gluonic mixing for either the 1 −− or the 0 ++ states.
