On the mixing amplitude of Jψ and vector glueball O Original Research Article

We study the mixing angle θOψ and mixing amplitude fOψ of View the MathML source and vector glueball O based on the framework of potential models of heavy quarks and constituent gluons. While the state vectors of View the MathML source and O are constructed from the wave functions of fewbody Schroedinger equations, the mixing dynamics is governed by perturbative QCD. We obtain a value of the mixing angle of |tan θOψ| ≈ 0.015 and the mixing amplitude of |fOψ(mOψ2)| ≈ 0.008 GeV2. Within our approximation scheme, this result is comparable with phenomenological analysis.
