This work offers the constraints on the anomalous neutral triple gauge couplings for the process \(e^+e^- \rightarrow ZZ \) 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.

通过使用非偏振和偏振光束 $$e^+e^- \rightarrow ZZ $$ 过程搜索反常 ZZZ 和 $$ZZ\gamma $$ 规范耦合

这项工作为 CLIC 上\(\sqrt{s}=3\) TeV的过程\(e^+e^- \rightarrow ZZ \)提供了反常中性三规范耦合的约束。我们的分析考虑了现实的 CLIC 探测器环境及其影响。该研究计划将产生的Z玻色子衰变为一对带电轻子(电子或μ子)和中微子对。异常中性三规范耦合定义了CP破坏\(C_{\widetilde{B}W}/{\Lambda ^4}\)耦合和三个CP守恒\(C_{WW}/{\Lambda ^ 4}\)\(C_{BW}/{\Lambda ^4}\)\(C_{BB}/{\Lambda ^4}\)耦合得到。此外,还研究了这些计算中入射电子束偏振的影响和优点。
