Abstract

Results on inclusive Ks 0 production in e+e- annihilation at mean center-of-mass energies of 9.4, 12.0 and 30 GeV are presented. The ratio R(K0) = 2σ(Ks 0)/σμμ rises from 3.10 ± 0.75 at √s = 9.4 GeV to 5.6 ± 1.2 at √s = 30 GeV, corresponding to an approximately constant K0/charged-particle ratio of 0.12 ± 0.02. A similar ratio for K0/ charged particle is observed for direct hadronic decays of the Υ{hooked}.
