    Paper

    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.
