N2 - The branching fraction of relative to all hadronic decays of the Z has been measured using event shape variables to preferentially select 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 is measured.
