$K^{*}{\mathrm{}\left(892\right)\mathrm{}}^0$ production in relativistic heavy ion collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=130\mathrm{}\mathrm{GeV}$

We report the first observation of $K^{*}{\mathrm{}\left(892\right)\mathrm{}}^0\to \pi K$ in relativistic heavy ion collisions. The transverse momentum spectrum of ${(K}^{*0}+K^{*0})/2\mathrm{}$ from central $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=130\mathrm{}\mathrm{GeV}$ is presented. The ratios of the $K^{*0}$ yield derived from these data to the yields of negative hadrons, charged kaons, and $\phi$ mesons have been measured in central and minimum bias collisions and compared with model predictions and comparable $e^{+}{e}^{-},$ $pp,$ 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.
