Hyperon production in Pb+Pb collisions at the CERN-SPS

Abstract

New results on the production of Xi and Omega hyperons in Pb+Pb interactions at 40AGeV and Lambda at 30AGeV are presented. Transverse mass spectra as well as rapidity spectra of these hyperons are shown and compared to previously measured data at different beam energies. The energy dependence of hyperon production (4pi yields) is discussed. Additionally, the centrality dependence of Xi^{-} production at 40AGeV is presented.
