The transverse mass spectra and midrapidity yields for Ξs and ω are presented. For the 10% most central collisions, the Ξ+/h- ratio increases from the Super Proton Synchrotron to the Relativistic Heavy Ion Collider energies while the Ξ-/h- stays approximately constant. A hydrodynamically inspired model fit to the H spectra, which assumes a thermalized source, seems to indicate that these multistrange particles experience a significant transverse flow effect, but are emitted when the system is hotter and the flow is smaller than values obtained from a combined fit to π, K, p, and Λs.
