Abstract:
We report the first observation of K(892)0πKK^{\star}(892)^{0}\to\pi K in relativistic heavy ion collisions. The transverse momentum spectrum of (K0+Kˉ0)/2(K^{\star0}+\bar{K}^{\star0})/2 from central Au+Au collisions at sNN=130\sqrt{s_{_{NN}}}=130 GeV is presented. The ratios of the K0K^{\star0} yield derived from these data to the yields of negative hadrons, charged kaons, and ϕ\phi mesons have been measured in central and minimum bias collisions and compared with model predictions and comparable e+ee^{+}e^{-}, pppp, and pˉp\bar{p}p results. The data indicate no dramatic reduction of K0K^{\star0} production in relativistic heavy ion collisions despite expected losses due to rescattering effects.
