Measurement of the branching ratios of the tau into leptons with the L3 detector at LEP
The branching ratios of the tau into leptons are measured using data collected from 1991–1994 by the L3 detector at LEP, running at √ s ≈ M z. The branching ratios of the decays τ→e¯ v¯ ev τ and τ→u¯ v¯ uv τ are obtained to be (17.67 ± 0.14 ± 0.13)% and (17.34 ±0.15 ± 0.15)%, respectively. The resul...
