Abstract
Decays of ψ are studied in a resonance-domination model. The Okubo-Zweig-Iizuka rule is realized dynamically by the propagation of quarkless mesons. Free parameters in the model are fixed by using available experimental data. Then a number of specific predictions are made, which test the dynamical scheme. In particular, suggestions for where to look for the quarkless mesons as resonant enhancements in spectra are discussed quantitatively.
