dc.description.abstractPresented here are the results of analysis of data for Au+Au at 130 GeV per nucleon pair. The data were taken by the STAR detector at RHIC. Production properties of Ξ− and its anti-particle are investigated through the measurement of ratios and yields, which are compared to previous SPS results as well as various model predictions. An anti-particle to particle ratio of 0.85±0.03(stat.)±0.05(sys.) is found for the 10% most central events. An exponential fit to the transverse mass spectra results in mid-rapidity yields and inverse slope parameters of dN/dy = 1.98±0.08(stat.) and T = 358±7(stat.) for the particle, and dN/dy = 1.73±0.07(stat.) and T = 357±7(stat.) for the anti-particle. Systematic errors for the fit results are estimated to be ∼ 20%. The ratio, yields, and inverse slope parameters are observed to be greater than SPS measurements from P b + P b collisions at 17.3 GeV per nucleon pair, indicating smaller net baryon content at mid-rapidity and hotter initial temperatures from the collisions at RHIC.
