Summary: Hyperons and kshorts were found in various data sets. Track embedding was used to calculate efficiencies, and results when possible were compared to HERWIG. C-taus as well as widths were measured. For the jet sets, the kshort and hyperon must orginate from within 5.0 cm of the jet vertex as well as be within a 0.7 cone. In addition, jets were corrected with underlying event and out-of-cone corrections. Track embedding used the track density distribution which depends on the energy of the jet. Properties of jets, kshorts, and hyperons were compared with jets not containing hyperons and kshorts. Muons, electrons, and photons using standard cuts from which W/Z/photon samples were extracted. In the W/Z/photon sample, few kshorts and hyperons were found inside jets. |
