The new results on hyperon production in Pb-Pb collisions at 158 A GeV/c and 40 A GeV/c are presented. Publisher Summary This chapter discusses the yields of hyperon in Pb–Pb collisions from the NA57 experiment. The aim of NA57 was to study the dependence of the strangeness enhancement on the interaction volume and the collision energy per incoming nucleon. The centrality range of the NA57 experiment extended down to a limit of about 50 wounded nucleons. The experiment collected data using 158 and 40 A GeV/c beams at the CERN SPS. There was indication of an increase of the enhancements with the centrality of the collisions. The data were corrected for acceptance and efficiency losses by calculating weight for each particle with a GEANT-based Monte-Carlo simulation.
