Production of Charged Pi-plus-minus, K-plus-minus and p/anti-p in Hadronic Z0 Decays
- SLAC
We present improved measurements of identified charged hadron production over a wide momentum range at SLD, using the Cherenkov Ring Imaging Detector to identify clean samples of charged pions, kaons and protons. In addition to studying flavor-inclusive Z{sup 0} decays, we compare the production in light, c and b flavor events, and present a new comparison of light-quark and gluon jets, selected using the SLD vertex detector. Also, we update our 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.
