Measurement of the Michel parameters and the tau neutrino helicity in the tau lepton decays
A measurement of the Michel parameters and the average $\nu_\tau$ helicity in $\tau$ lepton decays is described. The data analyzed, collected with the ALEPH detector at LEP during the years 1991 to 1995, corresponds to a total integrated luminosity of 155\,$\text{pb}^{-1}$. No significant deviation...

| Sumario: | A measurement of the Michel parameters and the average $\nu_\tau$ helicity in $\tau$ lepton decays is described. The data analyzed, collected with the ALEPH detector at LEP during the years 1991 to 1995, corresponds to a total integrated luminosity of 155\,$\text{pb}^{-1}$. No significant deviation from the Standard Model assumption of the \vma{} structure of the weak interaction is observed. |
