Özet

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, and d i _ of the ti-lepton, through the tau pair production channels pp -> p tau(tau) over bar gamma p, e(-)p -> (e)- tau(tau) over bar gamma p and e(+)e(-) tau(tau) over bar gamma e via the y*y* -> tau(+)tau(-)gamma 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 tau-lepton (a) over tilde (tau) = [-0.00128, 0.00105] and vertical bar(d) over tilde (tau)(ecm)I = 6.4394 x 10(-18) at the 95% Confidence Level. Our results also project better sensitivity than those reported by the DELPHI and BELLE collaborations.
