Limits on the Dipole Moments of the $τ$-Lepton via the Process $e^{+}e^{-}\to τ^+ τ^- γin a Left-Right Symmetric Model
Limits on the anomalous magnetic moment and the electric dipole moment of the $τ$ lepton are calculated through the reaction $e^{+}e^{-}\to τ^+ τ^- γ$ at the $Z_1$-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.
