Abstract
We address the problem of observed charmonium decays which should be f orbidden in perturbative QCD. We examine the model in which these deca ys proceed through a gluonic component of the J/psi and the eta(c), ar ising from a mixing of (ccBAR) and glueball states. We give some bound s on the values of the mixing angles and propose the study of the ppBA R-->phiphi reaction at square-root s congruent-to 3 GeV as an independ ent test of the model.
