    • Abstract


      The limits on the anomalous magnetic and electric dipole moments of the $\nu_{\tau}$ through the reaction $e^{+} e^{-} \rightarrow \nu \bar{\nu} \gamma$ at the $Z_{1}$-pole, and in the framework of a 331 model are obtained. The results are based on the data reported by the L3 Collaboration at LEP. We find that the bounds are almost independent of the mixing angle 𝜙 of the model in the allowed range for this parameter.
