Abstract

We investigate the dipole moments of the tau- neutrino at high-energy and high luminosity at linear electron positron colliders, such as CLIC or ILC through the analysis of the reaction e⁺ e^-→ ν ν γ in the framework of the SU(4)_L × U(1)_X model. The limits on dipole moment were obtained for integrated luminosity of \calL= 500-2000 fb^-1 and center of mass between 0.5 and 3.0 TeV. The estimated limits for the tau-neutrino magnetic and electric dipole moments are improved by 2-3 orders of magnitude and complement previous studies on the dipole moments.
