The authors have measured the differential cross sections for the production of [pi]{sup {+-}}, K{sup {+-}}, K°, K{sup *}(892), [phi](1020), p and [Lambda] in hadronic Z° decays and in subsets of flavor-tagged Z° → light-flavor (u{bar u}, d{bar d}, or s{bar s}), Z° → c{bar c} and Z° → b{bar b} events. Charged hadrons were identified with the SLD Cherenkov Ring Imaging Detector. A vertex detector was employed to select flavor-enriched samples, and the polarized electron beam from SLC was used to tag quark and antiquark jets. The authors observes a flavor dependence in the hadron fragmentation functions. They also present evidence for leading particle production in hadronic decays of the Z° boson to light-flavor jets and a direct measurement of the strangeness suppression factor [gamma]{sub s}.
