Abstract

We investigate the effects induced by excited leptons, at the one-loop level, in the anomalous magnetic and weak-magnetic form factors of the leptons. In particular, we compute their contributions to the weak-magnetic moment of the τ lepton, which can be measured on the Z peak, and we compare it with the contributions to gμ - 2, measured at low energies.
