Perturbative QCD Forbidden Charmonium Decays and Gluonia
Abstract
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/ and the ηc, arising from a mixing of (c c) and glueball states. We give some bounds on the values of the mixing angles and propose the study of the p p φ φ reaction, at s 3 GeV, as an independent test of the model.
