Strangeness production in proton proton collisions close to threshold
Strangeness production in proton proton collisions close to threshold
Exclusive data on the reactions pp --> ppK(+)K(-) and pp --> pK(+Lambda)/Sigma(0) have been taken at the cooler synchrotron COSY close to threshold.At equal excess energies, an enhancement of the Lambda/Sigma(0) ratio by one order of magnitude has been observed compared to data at higher exces...

Exclusive data on the reactions pp --> ppK(+)K(-) and pp --> pK(+Lambda)/Sigma(0) have been taken at the cooler synchrotron COSY close to threshold.At equal excess energies, an enhancement of the Lambda/Sigma(0) ratio by one order of magnitude has been observed compared to data at higher excess energies. New results obtained at the COSY-11 facility explore the transition region between this low-energy Sigma(0) suppression and excess energies of 60 MeV.A first total cross section for elementary antikaon production below the phi threshold has been determined, two orders of magnitude smaller compared to kaon production at the same excess energy. |
