In this paper, we present detailed studies for measuring the production cross sections and setting model independent limits on the anomalous magnetic and electric dipole moments and of the τ-lepton, through the tau pair production channels , and via the γ∗γ∗→ τ+τ−γ subprocess. Measurements of the anomalous electromagnetic couplings of the tau-lepton provide an excellent opportunity to probe extensions of the Standard Model. We found that of the three colliders considered LHC, FCC-he and CLIC, the prediction of the future CLIC at high energy and high luminosity should provide the best sensitivity on the dipole moments of the τ-lepton and at the 95% Confidence Level. Our results also project better sensitivity than those reported by the DELPHI and BELLE collaborations.
