Meson-Baryon Couplings in a Quark Model

The widths for decay of low-lying baryons of negative parity into baryon plus pseudoscalar meson are determined in a quark model and extensively compared with experiment. One conclusion is that ${\Xi }^{*}\mathrm{}\left(1816\right)\mathrm{}$ is not in an octet with $N^{*}\mathrm{}\left(1518\right)\mathrm{}$, ${Y_1}^{*}\mathrm{}\left(1660\right)\mathrm{}$. A second prediction is a kinematical factor in $s$-wave decay enhancing the decay into high-mass mesons ($K$ and $\eta$ over $\eta$), which provides a qualitative reason for $\eta$ peaks at threshold. Properties of the many missing baryon resonances are discussed. Channels appropriate for the search for some of these are indicated.
