摘要：

Measurements are presented of the inclusive cross section for K* (892)+/- production in hadronic decays of the Z0 using a sample of about half a million events recorded with the OPAL experiment at LEP. Charged K* mesons are reconstructed in the decay channel K(S)0pi+/-. A mean rate of 0.72 +/- 0.02 +/- 0.08 K*+/- mesons per hadronic event is found. Comparison of the results with predictions of the JETSET and HERWIG models shows that JETSET overestimates the K*+/- production cross section while HERWIG is consistent with the data.
