摘要：

A study of hyperon production in fully reconstructed proton-proton interactions at 28 GeV/c (root 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 Lambda production reactions. We note the similarities between Lambda reactions and other families of reactions, and show that this surprisingly simple model can be easily adapted to Xi(-) production reactions, The only significant difference between the Lambda and Xi(-) data is the observation that Lambda hyperons are produced as leading particles, whereas Xi(-) hyperons are not. Production cross sections for eight high-multiplicity hyperon reactions are presented.
