Search for the anomalous $ZZZ$ and $ZZ\gamma$ 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 $C_{\widetilde{B}W}/{\Lambda^4}$ coupling and three $CP$-conserving $C_{WW}/{\Lambda^4}$, $C_{BW}/{\Lambda^4}$, and $C_{BB}/{\Lambda^4}$ couplings are obtained. Also, the effects and advantages of polarization for incoming electron beams in these calculations are investigated.
