International Workshop on Neutrino Factories, Super Beams and Beta Beams

Using as an input the data obtained by the L3 Collaboration for the reaction e^+e^- --> \nu\bar\nu\gamma, we obtained limits on the electromagnetic dipole moments of the tau-neutrino in the context of a Simplest Little Higgs Model (SLHM). Our bounds on the electromagnetic moments are consistent with the bounds obtained by the L3 Collaboration for the reaction e^+e^- --> \nu\bar\nu\gamma. In addition, we obtained a limit on the characteristic energy scale of the model: f ≥ 5.5 TeV, which is competitive with those reported in the literature. Our work complements other studies on the electromagnetic dipole moments of the tau-neutrino and on the characteristic energy scale of the model f.
