摘要
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(+)Sigma(0), and pp -> nK(+)Sigma(+) are shown. Excitation furictions from threshold up to about 90 MeV excess energies have been evaluated with high precision for the Lambda and Sigma(0) production. The Lambda p and Sigma(0)p final state interactions were extracted. The Sigma(+) production was measured at 13 and 60 MeV excess energies.
