Abstract
Measurements are presented of the inclusive cross section for K (892)
+/- production in hadronic decays of the Z0 using a sample of about ha
lf a million events recorded with the OPAL experiment at LEP. Charged
K mesons are reconstructed in the decay channel K(S)0pi+/-. A mean ra
te 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 m
odels shows that JETSET overestimates the K+/- production cross secti
on while HERWIG is consistent with the data.
