摘要：

We address the problem of observed charmonium decays which should be forbidden in perturbative QCD. We examine the model in which these decays proceed through a gluonic component of the J/psi and the eta(c), arising from a mixing of (ccBAR) and glueball states. We give some bounds on the values of the mixing angles and propose the study of the ppBAR-->phiphi reaction at square-root s congruent-to 3 GeV as an independent test of the model.
