The Σ − p and Σ − d total cross sections have been measured to a statistical accuracy of ±1% and ±0.5%, respectively, at five momenta from 74.5 to 136.9 GeV/ c , using the hyperon beam at the CERN SPS. The Ξ − p and Ξ − d total cross sections have also been measured to the same statistical accuracy at 101.5 and 133.8 GeV/ c . The systematic uncertainty at each momentum is estimated to be of the order of ±0.5%. The hyperon-nucleon cross sections are shown to be rising with energy, and the data are compared with various phenomenological models.
