Abstract

We study the sensitivity to anomalous quartic ZZγγ couplings through the processes e⁺e^-→ Z Z γ, e⁺e^- → e⁺γ^* e^- → e⁺ Z Z e^- and e⁺e^- → e⁺γ^* γ^* e^- → e⁺ Z Z e^- at the CLIC. We find 95% confidence level bounds on these coupling parameters defining by the dimension-six operators. The best bounds on the anomalous ZZγγ couplings among the three processes are obtained from e⁺e^-→ Z Z γ at a center of mass energy of 3 TeV and an integrated luminosity of 590 fb^-1. We show that the best bounds obtained on both the anomalous coupling parameters are of the order of 10^-8 GeV^-2, significantly improving the current bounds.
