Abstract

We study the $K^{+} p \to I ¨ ^{+} K^{+} n$ reaction with some kinematics suited to the production of the $I^^{+}$ resonance recently observed. We show that, independently of the quantum numbers of the $I^^{+}$ , a resonance signal is always observed in the $K^{+}$ forward direction. In addition, we also show how a combined consideration of the strength at the peak, and the angular dependence of polarization observables can help determine the $I^^{+}$ quantum numbers using the present reaction.
