    Abstract

    The multiplicities per event of π± and K± are measured separately for e+e- annihilation into cc, bb, and light quark pairs at Ecm=29 GeV. The K± multiplicity is higher for heavy quark events than for light quark events. The π± multiplicity and the π± scaled differential cross section at low x=Ebeam/Ebeam are found to be higher for bb events than for other events.
