Abstract

We show that an SU(4) quark-gluon model is a specific realization of a scaling rule proposed by the authors for understanding hadronic production of heavy particles, including the recently discovered ψ particles. The model leads to predominantly associated production of φ and ψ (e.g., pairs). We emphasize that tests of the charmonium picture for ψ particles can be made independently by looking to see whether φ mesons are predominantly associatively produced.
