To improve the theoretical prediction of the anomalous dipole moments of the τ-neutrino, we have carried out a study through the processes e+e−→(γ,Z)→ντν¯τγ and γe−→τν¯τνe, which represent an excellent and useful option in determination of these anomalous parameters. Furthermore, we consider the effective Lagrangian formalism which induces contributions to the dipole moments of the tau-neutrino. To study the potential of the processes e+e−→(γ,Z)→ντν¯τγ and γe−→τν¯τνe we apply a future high-energy and high-luminosity linear electron-positron collider, such as the CLIC, with s=380, 1500, 3000 GeV and L=10, 50, 100, 200, 500, 1000, 1500, 2000, 3000 fb−1, and we consider systematic uncertainties of δsys=0%, 5%, 10%. Furthermore, we including initial state radiation plus beamstrahlung effects. With these elements, we present a comprehensive and detailed sensitivity study on the total cross section of the processes e+e−→(γ,Z)→ντν¯τγ and γe−→τν¯τνe, as well as on the dipole moments κ˜ντ and d˜ντ at the 95% C.L., showing the feasibility of such processes at the CLIC at the e+e− and γe− modes with unpolarized and polarized electron-positron beams.
