Description of strange particle production in Au+Au collisions ofsNN=130GeV in a single-freeze-out model

Abstract

Strange particle ratios and $p_{\perp }$ spectra are calculated in a thermal model with single freeze-out, previously used successfully to describe nonstrange particle production at RHIC. The model and the recently released data for $\phi ,$ $\Lambda ,$ $\overline{\Lambda },$ and $K^{*}{\mathrm{}\left(892\right)\mathrm{}}^0$ are in very satisfactory agreement, showing that the thermal approach can be used to describe the strangeness production at RHIC.
