Abstract
Expressions are derived for the differential probability for the decay τ → e(μ). The possibly nonzero mass of ντ and the polarizations of both the decaying lepton and the charged lepton which is produced are all taken into account. A quantitative analysis is carried out for various masses of the τ neutrino and for various energies of the lepton emitted during the decay.
