摘要:
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.
