摘要
We report the first observation of K*(892)0 → πK in relativistic heavy ion collisions. The transverse momentum spectrum of (K*0+K̄*0)/2 from Central Au+Au collisions at √SNN = 130 GeV is presented. The ratios of the K*0 yield derived from these data to the yields of negative hadrons, charged kaons, and Φ mesons have been measured in central and minimum bias collisions and compared with model predictions and comparable e+e-, pp, and p̄p results. The data indicate no dramatic reduction of K*0 production in relativistic heavy ion collisions despite expected losses due to rescattering effects.
