Limits on the Dipole Moments of the $\tau$-Lepton via the Process $e^{+}e^{-}\to τ^+ τ^- γin a Left-Right Symmetric Model

Abstract

Limits on the anomalous magnetic moment and the electric dipole moment of the $\tau$ lepton are calculated through the reaction $e^{+}{e}^{-}\to {\tau }^{+}{\tau }^{-}\gamma$ 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 $\varphi$, the effect of this angle on the dipole moments is quite small.
