Description
We use QCD Laplace sum-rule to explore meson-hybrid mixing in vector heavy quarkonium. Our cross-correlator calculation supplements perturbation theory with non-perturbative corrections proportional to the four-dimensional and six-dimensional gluon condensates and the six-dimensional quark condensate. After forming the Laplace sum-rule we use experimentally determined hadronic masses to build several single- and multi-resonance models of the $c\overline{c}$ and $b\overline{b}$ mass spectra. These models and the QCD Laplace sum-rule are then used to probe resonances for meson-hybrid mixing. Observations and results of the analysis will be presented.
