Abstract

The branching fraction of Z → bb relative to all hadronic decays of the Z has been measured using event shape variables to preferentially select Z → bb events. The method chosen applies a combination of shape discriminators and the selection of high transverse momentum leptons to event hemispheres. From a sample of 440 000 hadronic Z decays collected with the ALEPH detector at LEP, the ration Γ_bb Γ_had = 0.228±0.005(stat.)±0.005(syst.) is measured.

N2 - The branching fraction of Z → bb relative to all hadronic decays of the Z has been measured using event shape variables to preferentially select Z → bb events. The method chosen applies a combination of shape discriminators and the selection of high transverse momentum leptons to event hemispheres. From a sample of 440 000 hadronic Z decays collected with the ALEPH detector at LEP, the ration Γbb Γhad = 0.228±0.005(stat.)±0.005(syst.) is measured.
