Polarization and forward-backward asymmetry of Lambda baryons in hadronic Z(0) decays

摘要: The longitudinal polarization, the transverse and forward-backward asymmetry of \(\Lambda\) baryons, have been measured using a sample 4.34 million hadronic \(\mathrm{Z}^0\) decays collected with OPAL detector at LEP between 1990 1995. These results are important as an aid to understanding hadronization mechanisms. Significant polarization has observed intermediate high momentum. For \(x_E\) (\(\equiv 2 E_{\Lambda}/\sqrt{s}) >\) 0.3, be \(-32.9 \pm 5.5 \) (stat) \(\pm\) 5.2 (syst)%. We no polarization. A significant can described by JETSET model.
