Description

The ratio of branching fractions of the W decaying to τ and e leptons is measured using anti pp collisions at √s=630 GeV. The ratio of the electroweak charged current couplings to the W is then determined to be gτW/geW=0.997±0.056(stat.)±0.042(syst.). The decay mode Z→τ+τ- is observed and also found to be consistent with e-τ universality. (orig.)
