Abstract

Mid-rapidity Omega and anti-Omega production in Au+Au collisions at RHIC is studied with the STAR experiment. We report preliminary results on yields and spectra at

\sqrt{s_{NN}}

= 130 and 200 GeV. Production relative to negatively charged hadrons (h-) as well as thermal freeze-out and collective expansion are discussed.Comment: 4 pages, 5 figures, 1 table, Contribution to Quark Matter 2002, Nantes, France, July 200
