Abstract

We have performed a hyperon-proton scattering experiment with a scintillating fiber active target. The Σ-p, Ap and Σ+p scattering have been studied with the same experimental setup. In this paper, we present the differential cross sections of the Σ-p elastic scattering in the momentum region from 400 to 700 MeV/c. This is the first measurement of the Σ-p elastic scattering in the momentum region where the P- and higher waves contributions are important. The present data are in good agreement with the one boson exchange model (Bonn-Jülich model A) and the quark cluster model (FSS of Kyoto-Niigata model).
