Abstract

Total and differential $K^{0}$ corss sections are presented from $e^{+} e^{-}$ collisions at $\sqrt{s} = 29$ GeV in the High Resolution Spectrometer detector. $K^{0}$ and charged-particle distributions are compared in a study of the hadronization of quarks of known flavor. Ecents of the reaction $e^{+} e^{-} \to c \bar{c}$ are tagged by identifying $D^{*}' s$ while $u \bar{u}$ , $d \bar{d}$ , or $s \bar{s}$ events are tagged through the identification of a charged particle with fractional momentum near 1. Parton-shower models with cluster and string fragmentation are compared with these data. Also, certain particle scaling tests are performed using the quark-flavor tags. In addition, $K^{0}$ production in two- and three-jet events is compared to these models.
