On the mixing amplitude of J/psi and vector glueball O

摘要

We study the mixing angle theta(O psi) and mixing amplitude f(O psi) of J/psi and vector glueball O based on the framework of potential models of heavy quarks and constituent gluons. While the state Vectors of J/psi, and O are constructed from the wave functions of few-body Schroedinger equations, the mixing dynamics is governed by perturbative QCD. We obtain a value of the mixing angle of an theta(O psi) approximate to 0.015 and the mixing amplitude of (O psi)(m(O psi)(2)) approximate to 0.008 GeV2. Within our approximation scheme, this result is comparable with phenomenological analysis. [References: 10]
