A measurement of the topological branching ratios of the $\tau$ particle at the $Z^0$ peak
A determination of the topological branching ratios of the $\tau$ lepton has been performed using a data. sample corresponding to an integrated luminosity of 22.9 pb-1 collected with the DELPHI detector operating at LEP in 1992. The results for the inclusive branching ratios assuming B1 + B3 + B5 =...

| Sumario: | A determination of the topological branching ratios of the $\tau$ lepton has been performed using a data. sample corresponding to an integrated luminosity of 22.9 pb-1 collected with the DELPHI detector operating at LEP in 1992. The results for the inclusive branching ratios assuming B1 + B3 + B5 = 100% are ; B1 = 85.26 ± 0.23 ( stat ) ± 0.15 ( syst ) % B3 = 14.37 ± 0.24 ( stat ) ± 0.16 ( syst ) % B5 = 0.37 ± 0.10 ( stat ) ± 0.06 ( syst ) % |
