$K^{\star }(892{)}^0$ Production in Relativistic Heavy Ion Collisions at $\sqrt{s_{{}_{NN}}}=130$ GeV

STAR Collaboration

We report the first observation of $K^{\star }(892{)}^0\to \pi K$ in relativistic heavy ion collisions. The transverse momentum spectrum of $(K^{\star 0}+{\bar{K}}^{\star 0})/2$ from centra…
