Using the $K^+p\to π^+K^+n$ reaction to determine the $Θ^+$ quantum numbers

Abstract

We study the $K^+p\to π^+K^+n$ reaction with some kinematics suited to the production of the $Θ^+$ resonance recently observed and show that the measurement of cross sections and polarization observables can shed light on the spin,isospin and parity of the $Θ^+$ state.
