Spectra and strong decays ofcc¯andbb¯states

Abstract
An outline is given for the description of heavy-quark-antiquark systems by means of a set of coupled Schrödinger equations in which permanently confined two-fermion channels are coupled to free two-boson channels. Only two-particle decays satisfying the Okubo-Zweig-Iizuka rule are taken into account. Within this context the equations make a simple determination of the spectra and decay parameters possible. A comparison with the data is presented.
