K*(892)0production in relativistic heavy ion collisions atsNN=130GeV

We report the first observation of ${K}^{*}{(892)}^{0}\ensuremath{\rightarrow}\ensuremath{\pi}K$ in relativistic heavy ion collisions. The transverse momentum spectrum of ${(K}^{*0}+{K}^{*0})/2$ from central $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=130\mathrm{GeV}$ is presented. The ratios of the ${K}^{*0}$ yield derived from these data to the yields of negative hadrons, charged kaons, and $\ensuremath{\varphi}$ mesons have been measured in central and minimum bias collisions and compared with model predictions and comparable ${e}^{+}{e}^{\ensuremath{-}},$ $pp,$ and $\overline{p}p$ results. The data indicate no dramatic reduction of ${K}^{*0}$ production in relativistic heavy ion collisions despite expected losses due to rescattering effects.
