It is demonstrated that measurements of photon asymmetry in the γn → K−K+n reaction, can most likely determine the parity of the newly discovered Θ+ pentaquark. We predict that if the parity of Θ+ is positive, the photon asymmetry is significantly positive; if the parity is negative, the photon asymmetry is significantly negative. If the background… (More)
