A hyperon-nucleon scattering experiment, KEK-PS E289, was carried out at the K2 beam line in KEK. We adopted a scintillating fiber active target as a hydrogen target for hyperon production and subsequent hyperon-nucleon scattering. We collected more data than in a previous experiment, KEK-PS E251. In this paper, the differential cross sections for ∑+ p elastic scattering in the incident momentum range from 350 to 750 MeV/c are presented and compared with theoretical predictions from the Nijmegen group (Nijmegen Soft Core 97) and the Kyoto-Niigata group (RGM-FSS and fss2).
