P13 phase shift in K+p reactions and an exotic resonance Z1*(1860)
Description
P13 partial wave amplitude of K+p elastic scattering is investigated from the information on the inelastic channels, KΔ (1236) and K (891)p in terms of the three channel N/D model. The calculated P13 phase shift shows a counterclockwise circle in the Argand diagram and has the maximum of phase shift versus energy at 1.15 GeV/c of kaon incident momentum. We argue that the exotic resonance Z1 , if it exists, is a highly inelastic resonance caused by the strong absorption through inelastic channels and is coupled very weakly with K+p elastic channel.
