Abstract: (APS)

Energy-dependent partial-wave amplitudes based on a coupled-channel (K+p, KΔ) K- matrix formalism are obtained for elastic K+p scattering up to Plab=2 GeV/c. The data used include new high-precision differential cross sections. A total of 42 parameters describing the l<~4 partial waves are used to fit 3822 data points and the best solution found has a χ2 per degree of freedom of 1.33. This solution exhibits a T-matrix Z* resonance pole in the P3 partial wave with mass coordinates 1787-i100 MeV.
