Production of strange particles in the hadronic decays of the Z 0

Production of strange particles in the hadronic decays of the Z 0

An analysis of the production of strange particles from the decays of the Z 0 boson into multihadronic final states is presented. The analysis is based on about 90 000 selected hadronic Z 0 decays collected by the DELPHI detector at LEP in 1990. K s 0, K ∗±, Λ( Λ) and Ξ − ( Ξ +) have been identified...

Zusammenfassung:An analysis of the production of strange particles from the decays of the Z 0 boson into multihadronic final states is presented. The analysis is based on about 90 000 selected hadronic Z 0 decays collected by the DELPHI detector at LEP in 1990. K s 0, K ∗±, Λ( Λ) and Ξ − ( Ξ +) have been identified by their characteristic decays. The measured production cross sections are compared with predictions of the Lund Monte Carlo tuned to data at PEP/PETRA energies.
