Strangeness $-2$ and $-3$ baryons in a constituent quark model

We apply a quark model developed in earlier work to the spectrum of baryons with strangeness $-2$ and $-3$. The model describes a number of well-established baryons successfully, and application to cascade baryons allows the quantum numbers of some known states to be deduced. [JLAB-THY-07-728]
