Quark hadronization probed by K0 mesons.

Total and differential ${K}^{0}$ corss sections are presented from ${e}^{+}{e}^{\ensuremath{-}}$ 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 ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}c\overline{c}$ are tagged by identifying ${D}^{*}'\mathrm{s}$ while $u\overline{u}$, $d\overline{d}$, or $s\overline{s}$ 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.
