摘要：

The production of K0 mesons in e+ e- interactions at center of mass energies in the region of the Z0 mass has been investigated with the OPAL detector at LEP. The rate is found to be 2.10 +/- 0.05 +/- 0.14 K0, Z0BAR per hadronic event. The predictions from the JETSET and HERWIG generators agree very well with both the rate and the scale invariant cross section (1/sigma(had)beta) (d-sigma/dx(E)) for K0 production. Comparisons of the inclusive momentum spectrum with predictions of an analytical QCD formula and with data from lower center of mass energies are presented.
