Abstract

We present a summary of measurements of strange particles performed by the experiment NA49 in inelastic p+p interactions, as well as semi-central C+C and Si+Si, central Pb+Pb, and minimum bias Pb+Pb collisions in the energy range sNN\sqrt{s_{NN}} = 6.3 - 17.3 GeV. New results on π\pi^{-}, K+K^{+} and KK^{-} production in minimum bias Pb+Pb collisions at sNN\sqrt{s_{NN}} = 8.7 and 17.3 are shown. Furthermore the strangeness enhancement factor at sNN\sqrt{s_{NN}} = 17.3 GeV is presented and compared to the results from NA57 and STAR. Energy dependence of strange particle yields normalized to pion yields is presented. New data on <K(892)0><K^{*}(892)^{0}> production are shown at sNN\sqrt{s_{NN}} = 17.3 GeV. Furthermore we present the energy dependence of K/πK/\pi and K/pK/p fluctuations. The data are compared with model predictions.
