Search for the anomalous $ZZZ$ and $ZZ{\hat{I}}^3$ gauge couplings through the process $e^{+}{e}^{-}\to ZZ$ with unpolarized and polarized beams

Abstract

This work offers the constraints on the anomalous neutral triple gauge couplings for the process $e^{+}{e}^{-}\to ZZ$ at the CLIC with $\sqrt{s}=3$ TeV. The realistic CLIC detector environments and their effects are considered in our analysis. The study is planned for the decays of produced $Z$ bosons to a pair of charged leptons (electrons or muons) and neutrino pairs. The bounds on the anomalous neutral triple gauge couplings defining $CP$-violating $C_{\tilde{B}W}/\hat{I}{›}^4$ coupling and three $CP$-conserving $C_{WW}/\hat{I}{›}^4$, $C_{BW}/\hat{I}{›}^4$, and $C_{BB}/\hat{I}{›}^4$ couplings are obtained. Also, the effects and advantages of polarization for incoming electron beams in these calculations are investigated.
