Abstract

Photon-photon reaction provides an excellent opportunity to isolate the tqγ vertex. For this purpose, we have examined the potential of the e^-e⁺→ e^-γ^*γ^*e⁺→ e^-tqe⁺→ e^-W bqe⁺ (γ^* is the Weizsacker-Williams photon and q=u,c) process to investigate the anomalous tqγ couplings in γ^*γ^* collisions at the CLIC. We have obtained 95% confidence level limits on the anomalous couplings for various values of the center-of-mass energy and integrated luminosity. We have shown that the limit on anomalous κ_tqγ coupling is more restricted with respect to current experimental limits.
