We investigate mixing between conventional mesons and hybrid mesons in vector and axial vector charmonium using the QCD sum-rules formalism. We compute meson-hybrid cross correlators within the operator product expansion, taking into account condensate contributions up to and including those of dimension-six as well as composite operator renormalization-induced diagrams. Using measured masses of charmonium states as input, we probe known resonances for nonzero coupling to both conventional meson and hybrid meson currents, a signal for meson-hybrid mixing.
