Abstract

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 as the ILC and CLIC. For our study we consider the process e⁺e^-→ ( Z, Z', γ) → ν_τ ν_τγ. For center-of-mass energies of √(s)=1000-3000\hspace0.8mmGeV and integrated luminosities of \cal L=500-2000\hspace0.8mmfb^-1, we derive 95 % \hspace1mm C.L. limits on the dipole moments |μ_ντ(μ_B)| ≤ 6.28 × 10^-9 and |d_ντ(e cm)| ≤ 1.21 × 10^-21 improve the existing limits by two or three orders of magnitude. Our study complements other studies on the dipole moments of the tau-neutrino at hadron and e⁺e^- colliders.
