Dipole moments of the tau neutrino via the process {e^{+}e^{-}rightarrow nubarnu gamma} in a 331 model

The limits on the anomalous magnetic and electric dipole moments of the ?? _?? 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 ? of the model in the allowed range for this parameter.
