Model Mixing

Limits on the anomalous magnetic moment and the electric dipole moment of the τ lepton are calculated through the reaction e+e-→τ+τ-γ at the Z1-pole and in the framework of a left–right symmetric model. The results are based on the recent data reported by the L3 collaboration at CERN LEP. Due to the stringent limit of the model mixing angle ϕ, the effect of this angle on the dipole moments is quite small.

Theoretical Uncertainty

The experimental precision of the anomalous magnetic moment of the muon has been improved to 0.5 part-per-million by the Brookhaven E821 experiment, similar to the theoretical uncertainty. In the same experiment, a new limit on the electric dipole moment of 2.8 × 10-19 e·cm (95% CL) was set. The experiment and plans to improve them are described.
