> 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
> transverse momentum 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.
