Abstract

A simple fragmentation model of hadronic collisions is used to study hyperon production. The fragmentation is visualised with the aid of the string model and string breaking is modelled using a simple Monte Carlo procedure. The strings are created via a Drell-Yan type quark-diquark fusion mechanism with another string being created among the spectator partons. With the fusion cross-sections assumed to have a logarithmics behaviour, a fair description ofdσ/dx F for λ production inpp and πp collisions over a wide energy range is obtained. The available Σ production data is modelled by assuming, in addition, that some Σ′s are the products of Λp* decay. Some observations are made on the differences betweenuu andud diquarks and on hyperon polarisations.
