• In this work we study the sensitivity on the anomalous magnetic and electric dipole moments of the tau neutrino in the framework of the SU(2)L×U(1)Y×U(1)B−L electroweak model at future e+e− linear colliders, such as the ILC and CLIC. For our study we consider the process e+e−→(Z,Z′,γ)→ντν¯τγ. For center-of-mass energies of s=1000–3000  GeV and integrated luminosities of L=500–2000  fb−1, we derive 95% C.L. limits on the dipole moments |μντ(μB)|≤6.28×10−9 and |dντ(ecm)|≤1.21×10−21, which improve on the existing limits by 2 to 3 orders of magnitude. Our study complements other studies on the dipole moments of the tau neutrino at hadron and e+e− colliders.
