    "abstract": "We review the status of the $S_{11}$ N$^*$ resonances in light of some recent\ntheoretical and phenomenological results. Whereas the quark model predicts two\nsuch resonances around 1.6 GeV, there is considerable evidence for a third\n$S_{11}$ resonance in this energy range. This suggests that a $K\\Sigma$ or\n$K\\Lambda$ quasi-bound state may indeed exist below the kaon production\nthreshold. We show that kaon production experiments, in particular $K^0$\nphotoproduction off nucleons, would be very sensitive to the existence of the\nthird $S_{11}$ resonance.",
