Abstract

The charged-particle multiplicity is measured for b-quark and light-quark (u, d, s) events in e⁺e^- annihilation at √s = 58 GeV. Two independent methods, lepton tagging and decay-length tagging, are applied to enrich b-quark events. These methods provide event samples having different concentrations of b-quark events. The mean charged multiplicity is measured to be 19.38 ± 0.27 ± 0.84 for b-quark events, and 15.91 ± 0.04 ± 0.70 for light-quark events. The results are compared with predictions of phenomenological and theoretical models.
