A study of hyperon production in fully reconstructed proton-proton interactions at 28 GeV/c (√s=7.3 GeV) is presented. Features of the data are presented with the aid of a phenomenological model, the LPM, that was developed to study Λ production reactions. We note the similarities between Λ reactions and other families of reactions, and show that this surprisingly simple model can be easily adapted to Ξ- production reactions. The only significant difference between the Λ and Ξ- data is the observation that Λ hyperons are produced as leading particles, whereas Ξ- hyperons are not. Production cross sections for eight high-multiplicity hyperon reactions are presented. © 1996 The American Physical Society.
