Summary
The resonance production of Δ, K(892), Σ(1385), Λ(1520) and φ from elementary p+p and Au+Au collisions at √{<i>s<i/>NN} = 200 GeV from the STAR experiment at RHIC is presented. Yields and spectra are discussed in terms of chemical and thermal freeze-out conditions. Thermal models do not describe sufficiently the yields of the resonance production in central Au+Au collisions. The approach which includes pseudo-elastic and elastic hadronic interactions after chemical freeze-out until thermal freeze-out suggests a time span of Δτ > 5 fm/c.
