The authors have updated their results on identified charged hadron production using the full SLD data sample of 550,000 hadronic Z{sup 0} decays taken between 1993 and 1998. The SLD Cherenkov Ring Imaging Detector allows the identification of clean samples of charged pions, kaons and protons over a wide momentum range, providing precise tests of perturbative QCD calculations and of fragmentation models. The authors have studied flavor-inclusive Z{sup 0} decays, as well as decays into light, c and b flavors, selected using the SLD vertex detector. In addition they have updated their comparison of hadron and antihadron production in light quark (rather than antiquark) jets, selected using the high SLC electron beam polarization. Differences between hadron and antihadron production at high momentum fraction provide precise measurements of leading particle production and new, stringent tests of fragmentation models.
