Recent results on strangeness production from NA49
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
= 6.3 - 17.3 GeV. New results on , and
production in minimum bias Pb+Pb collisions at = 8.7 and 17.3
are shown. Furthermore the strangeness enhancement factor at =
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 production are shown at = 17.3
GeV. Furthermore we present the energy dependence of and
fluctuations. The data are compared with model predictions.Comment: 9 pages, 7 figures, Submitted to J. Phys. G (Proceedings of the
