Strange baryon resonance production in $\sqrt{s_{NN}}=200$ GeV $p+p$ and $Au+Au$ collisions

Abstract

We report the measurements of $\Sigma (1385)$ and $\Lambda (1520)$ production in $p+p$ and $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV from the STAR collaboration. The yields and the $p_T$ spectra are presented and discussed in terms of chemical and thermal freeze-out conditions and compared to model predictions. Thermal and microscopic models do not adequately describe the yields of all the resonances produced in central $Au+Au$ collisions. Our results indicate that there may be a time-span between chemical and thermal freeze-out during which elastic hadronic interactions occur.
