Abstract

The branching fraction of View the MathML source relative to all hadronic decays of the Z has been measured using event shape variables to preferentially select View the MathML source 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 View the MathML source is measured.
