| dc.description | We obtain limits on the electromagnetic and weak dipole moments of the tau-lepton in the framework of a Left-Right symmetric model (LRSM) and a class of $E_6$ inspired models with an additional neutral vector boson $Z_θ$. Using as an input the data obtained by the L3 and OPAL Collaborations for the reaction $e^+e^-\to τ^+τ^-γ$, we get a stringent limit on the LRSM mixing angle $ϕ$, $-1.66\times 10^{-3}< ϕ<1.22\times 10^{-3}$, which in turn induces bounds on the tau weak dipole moments which are consistent with the bounds obtained recently by the DELPHI and ALEPH Collaborations from the reaction $e^+e^-\to τ^+τ^-$. We also get similar bounds for the weak dipole moments of the tau lepton in the framework of $E_6$ superstring models. | |
