摘要

我们以一种与模型无关的方式，探索了光子诱导的相互作用与γ*γ* → ZZ过程的潜力，从而利用标准模型有效场论来研究希格斯-高斯玻色子耦合的CP守恒和CP违反的六维算子。在 3 TeV 紧凑线性对撞机（CLIC）和 10 TeV μ介子对撞机（MuC）上分别以 5 和 10 ab-1 的综合光度讨论了反常 Hγγ 和 HZZ 耦合的存在。所有信号和相关背景事件都在MadGraph中生成，并通过PYTHIA进行粒子淋和强子化。使用在 Delphes 中调整的 CLIC 和 MuC 探测器卡对探测器效应进行了评估。我们报告了威尔逊系数 , , , , 的 95% 置信度限值，并将它们与实验和现象学限值进行了比较。

Study on the sensitivity of the Higgs boson couplings in photon–photon collision at CLIC and muon collider

In a model-independent way, we explore the potential of photon-induced interactions with the process γ*γ* → ZZ to investigate CP-conserving and CP-violating dimension-six operators of Higgs-gauge boson couplings using the standard model effective field theory. The existence of anomalous Hγγ and HZZ couplings is discussed at 3 TeV compact linear collider (CLIC) and 10 TeV muon collider (MuC) with integrated luminosities of 5 and 10 ab−1, respectively. All signal and relevant background events are generated in MadGraph and passed through PYTHIA for parton showering and hadronization. The detector effects are evaluated using CLIC and MuC detector cards tuned in Delphes. We report the 95% confidence level limits on the Wilson coefficients , , , , , and and compare them with the experimental and phenomenological limits.
