Using the $K^{+}p\to {\pi }^{+}{K}^{+}n$ reaction to determine the ${\Theta }^{+}$ quantum numbers

E. Oset, T. Hyodo, A. Hosaka

We study the $K^{+}p\to {\pi }^{+}{K}^{+}n$ reaction with some kinematics suited to the production of the ${\Theta }^{+}$ resonance recently observed and show that the measurement of cross sections and p…
