Description
The one-loop electroweak radiative correction to the decay rate of the τ lepton into a neutrino plus hadrons is calculated. The correction includes a large logarithm of MZ/Mτ whose coefficient was calculated previously. The constant under the logarithm gives an additional electroweak correction of 0.1%. It is argued that modifications of this electroweak correction due to nonperturbative QCD effects are suppressed by powers of Mτ
