Compositeness Effects in the Anomalous Weak-Magnetic Moment of Leptons
M. C. Gonzalez-Garcia, S. F. Novaes
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. Using a general effective Lagrangian approach to describe the couplings of the excited leptons, 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.
