Abstract

Results on Λ,Λ̄,Ξ-, and Ξ̄+ production in central Pb+Pb reactions at 20A,30A,40A,80A, and 158A GeV are presented. The energy dependence of transverse mass spectra, rapidity spectra, and multiplicities is discussed. Comparisons to string hadronic models (UrQMD and HSD) and statistical hadron gas models are shown. Although the latter provide a reasonable description of all particle yields, the first class of models fails to match the Ξ- and Ξ̄+ multiplicities.
