$Measurements of the leptonic branching fractions of the tau$

Measurements of the leptonic branching fractions of the tau

Data collected with the DELPHI detector from 1993 to 1995 combined with previous DELPHI results for data from 1991 and 1992 yield the branching fractions B(τ → evv̄) = (17.877 ± 0.109stat ± 0.110sys)% and B(τ → μvv̄) = (17.325 ± 0.095stat ± 0.077sys)%.
