Abstract

The simple quark model describes astonishingly well the spectrum of ordinary mesons and baryons. A first non-trivial achievement is to account for the quantum numbers of the hadrons. The well-established states have non exotic quantum numbers, which correspond to q{sub 1}antiq{sub 2} or q{sub 1}q{sub 2}q{sub 3} configurations with all possible spin and angular momentum wave-functions. Quantitative models (bags, potentials ...) have even produced remarkable quantitive estimates of the mass spectrum. A crucial ingredient is flavour independence of the confining interaction which allows one, for instance, to describe simultaneously the cantic and bantib excitation spectra. In this review, we shall concentrate on states, which are stable under strong interactions. If they exist, they will offer clear experimental signatures, and for theorists, an ideal tool for studying the coherences of the interquark forces, as well as the weak decay of flavoured quarks in new environments.
