Sažetak
Results on Lambda, anti-Lambda, and Xi- production in centrality selected Pb+Pb reactions at 40A and 158A GeV and in near-central C+C and Si+Si reactions at 158A GeV are presented. Transverse mass spectra, rapidity spectra, and multiplicities in dependence of the system size are discussed. Comparisons to transport models (ultrarelativistic quantum molecular dynamics and hadron string dynamics) and to the core-corona approach are performed. Although Lambda and anti-Lambda production can be described by transport models reasonably well, these models do not agree with the Xi- measurements. However, the core-corona picture fits very well the system-size dependence of Lambda and Xi-, whereas it agrees less well with the anti-Lambda data.
