Strong and Weak Decays with Meson Emission in the Quark Model

Strong, electromagnetic, and weak decays are described in the independent-quark model as single quark transitions with no symmetry higher than isospin assumed for the interaction. Relations between quark model and symmetry predictions, e.g., $\mathrm{SU}{\mathrm{}\left(6\right)\mathrm{}}_W$, and the posslbility of experimental tests are discussed. Strong decays of a three-quark baryon supermultiplet with $L=2\mathrm{}$ are treated in detail. Many predictions are given which can provide tests of symmetries and of the model when more data are available. Present data indicate rough agreement, but are inconclusive.
