摘要
The one-loop electroweak radiative correction to the decay rate of the lepton into a neutrino plus hadrons is calculated. The correction includes a large logarithm of MZM 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 M. © 1990 The American Physical Society.
