论文摘要
惰性双线模型（IDM）是标准模型的简单扩展，引入了一个带有四个新的标量粒子的额外的Higgs Doublet。 IDM标量最轻的标量很稳定，是暗物质粒子的良好候选者。在实验中发现IDM标量在紧凑型线性碰撞器（CLIC）的潜力，即E $^{+} $ e $^{ - } $ collider作为CERN的下一代基础架构提议的两个高能量跑步阶段，在1.5 TEV和3 TEV Centre-Centre-Mass Energy进行了测试。使用GEANT4的完整检测器模拟，研究了对带电IDM标量的成对产生的CLIC敏感性，用于选定的高质量IDM基准方案和半leptonic最终状态。为了将完整的仿真结果推送到更广泛的IDM基准方案，将Delphes快速模拟框架定义的CLIC检测器模型进行了修改，以考虑到$γγ\ Rightarrow $所考虑的。梁引起的背景。该研究的结果表明，对于大多数考虑的基准场景，可以在CLIC上发现重型带电的IDM标量，直到1 TEV阶的质量。
The Inert Doublet Model (IDM) is a simple extension of the Standard Model, introducing an additional Higgs doublet that brings in four new scalar particles. The lightest of the IDM scalars is stable and is a good candidate for a dark matter particle. The potential of discovering the IDM scalars in the experiment at the Compact Linear Collider (CLIC), an e$^{+}$e$^{-}$ collider proposed as the next generation infrastructure at CERN, has been tested for two high-energy running stages, at 1.5 TeV and 3 TeV centre-of-mass energy. The CLIC sensitivity to pair-production of the charged IDM scalars was studied using the full detector simulation with GEANT4 for selected high-mass IDM benchmark scenarios and the semi-leptonic final state. To extrapolate full simulation results to a wider range of IDM benchmark scenarios, the CLIC detector model defined in the DELPHES fast simulation framework was modified to take into account the $γγ\rightarrow$ had. beam-induced background. Results of the study indicate that heavy charged IDM scalars can be discovered at CLIC for most of the considered benchmark scenarios, up to masses of the order of 1 TeV.
