Enhanced production of strange baryons and anti-baryons at central rapidity in S-W and S-z.sbnd;S with respect to p-A reactions has been reported by the CERN experiments WA85 and WA94. The WA97 experiment is extending such a study to PbPb collisions making use of the newly developed silicon pixel detectors. Results on Λ, Ξ− and Ω− production in PbPb collisions at 158 A GeV/c at central rapidity are presented. Transverse mass spectra and particle ratios are presented.

Abstract
Enhanced production of strange baryons and anti-baryons at central rapidity in S-W and S-z.sbnd;S with respect to p-A reactions has been reported by the CERN experiments WA85 and WA94. The WA97 experiment is extending such a study to PbPb collisions making use of the newly developed silicon pixel detectors. Results on Λ, Ξ− and Ω− production in PbPb collisions at 158 A GeV/c at central rapidity are presented. Transverse mass spectra and particle ratios are presented. Hyperon yields are given as a function of the collision centrality and compared with those obtained from p-Pb collisions using the same experimental setupFile in questo prodotto:
