Summary of the COSY-11 Measurements of Hyperon Production
Abstract
Description
The studies of hyperon production performed at COSY-11 are summarized. The results of the experiments in the reaction channels pp-->pK+Lambda, pp-->pK+Sigma0, and pp-->nK+Sigma+ are shown. Excitation functions fromthreshold up to about 90MeV excess energies have been evaluated with high precision for the Lambda and Sigma0 production. The Lambdap and Sigma0p final state interactions were extracted. The Sigma+ production was measured at 13 and 60 MeV excess energies.
