Search for the anomalous ZZZ and ZZγ gauge couplings through the process e^+e^- → ZZ with unpolarized and polarized beams

This work offers the constraints on the anomalous neutral triple gauge couplings for the process e^+e^- → ZZ at the CLIC with √(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_BW/Λ^4 coupling and three CP-conserving C_WW/Λ^4, C_BW/Λ^4, and C_BB/Λ^4 couplings are obtained. Also, the effects and advantages of polarization for incoming electron beams in these calculations are investigated.
