Figure 1

\pt distributions at midrapidity for \kzero, \lmb, \Xiboth, and \Omboth for multiplicity classes and \inelgz, as indicated. Statistical uncertainties are shown as error bars, the systematic ones as boxes. The bottom panels present the ratio of all spectra to the \inelgz one. The dashed curves show the Levy-Tsallis   fit to the \pt distributions.
