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 e + e - → Z Z at the CLIC with √s=3 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 C B ~ W / Λ 4 coupling and three CP -conserving CWW/Λ ⁴ C WW / Λ 4 , CBW/Λ ⁴ C BW / Λ 4 , and CBB/Λ ⁴ C BB / Λ 4 couplings are obtained. Also, the effects and advantages of polarization for incoming electron beams in these calculations are investigated.
