Abstract
The production of hyperons in Pb-Pb and p-Be interaction at 40 GeV/\ beam momentum has been measured by the NA57 experiment. Strange particle enhancements at 40 GeV/ are presented and compared to those measured at 158 GeV/. Their transverse mass spectra have been studied in the framework of the blast-wave model. The multiplicity of charged particles as a function of the energy is also discussed.
