Comparison of gluon and light quark jet particle yields.

Extensive data on hadron spectra across jet types.

Abstract

We present measurements of identified charged hadron production over a wide momentum range using the SLD Cherenkov Ring Imaging Detector. In addition to studying particle production in flavor-inclusive Z^0 decays, we compare the production in decays into light, c and b flavor events. We also examine particle production in gluon jets with that in light quark jets. The jet flavors are selected by using displaced vertex information.
