Abstract: (Springer)

A measurement of the Michel parameters and the average

\nu_\tau

helicity in

\tau

lepton decays is described. The data was co

electron positron: colliding beams
electron positron: annihilation
Z0: electroproduction
tau: pair production
tau: leptonic decay
Michel parameter
tau: semileptonic decay
neutrino/tau: helicity
model: weak interaction
electroweak interaction: validity test
