Abstract

New results of the NA49 collaboration on strange particle production are presented. Rapidity and transverse mass spectra as well as total multiplicities are discussed. The study of their evolution from AGS over SPS to the highest RHIC energy reveals a couple of interesting features. These include a sudden change in the energy dependence of the m_t-spectra and of the yields of strange hadrons around 30 AGeV. Also, fluctuations of the (K+ + K-)/(pi+ + pi-) ratio and the (p + barp)/(pi+ + pi-) ratio, as well as the v₂ of Lambda in Pb+Pb collsions at 158 AGeV are discussed.
