| dc.description | We review the status of the $S_{11}$ N$^*$ resonances in light of some recent theoretical and phenomenological results. Whereas the quark model predicts two such resonances around 1.6 GeV, there is considerable evidence for a third $S_{11}$ resonance in this energy range. This suggests that a $KΣ$ or $KΛ$ quasi-bound state may indeed exist below the kaon production threshold. We show that kaon production experiments, in particular $K^0$ photoproduction off nucleons, would be very sensitive to the existence of the third $S_{11}$ resonance. | |
