Measurement of Michel Parameters and $\tau$ Neutrino Helicity in $Z^{0} \to \tau^{+}\tau^{-}$

Data sets comprising 24 pb**-1 collected with the ALEPH detector a LEP in 1990 to 1992 were used to measure the Michel Parameters and the mean tau polarisation. The assumption of v and a type couplings in the production of the tau pairs allowed the correlation of the heli- cities of the tau+ and tau...
