• 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 a ~ τ and d ~ τ of the τ-lepton, through the tau pair production channels p p → p τ τ ¯ γ p , e - p → e - τ τ ¯ γ p and e + e - → e + τ τ ¯ γ e - 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 a ~ τ = [ - 0.00128 , 0.00105 ] and | d ~ τ ( ecm ) | = 6.4394 × 10 - 18 at the 95% Confidence Level. Our results also project better sensitivity than those reported by the DELPHI and BELLE collaborations.
