Departures of the vector boson masses from the predictions of the standard model are studied as a possible window to new physics. An estimate of the mass shifts is presented in two different models recently proposed to explain the anomalous ℓ+ℓ-γ events seen at the collider. In both cases there is a cancellation of the leading term and the mass shifts are of the same order of magnitude as the standard radiative corrections in one of the models (scalar particle) while they are too small to be detectable in the other case (excited lepton). © 1985.
