# 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 root 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
