Abstract

We report on inclusive K0 production in the region of the upsilon resonances (9.4-10.6 GeV). The K0 yield for the resonances and continuum below the BB threshold is found to be constant at 0.82 ± 0.10 K0 per observed hadronic event. At the Υ{hooked}(4S), however, the K0 yield is significantly higher, 1.58 ± 0.35. This increase in K0 production and the differential cross section dσ/dp of kaons are consistent with BB decay of the Υ{hooked}(4S) resonance with the bottom quarks subsequently decaying primarily into charmed quarks. © 1982.
