论文摘要
惰性双线模型（IDM）是具有扩展标量扇区的标准模型（SM）以外的最简单的扩展之一，该扇区提供了标量暗物质粒子的候选者。在本文中，我们调查了$γγ$ collider的双重充电Higgs生产。通过扫描整个参数空间，我们获得了与暗物质的正确遗物丰度相对应的参数点。应用了所有理论和实验约束后，存在暗物质的参数空间受到极大限制。我们对IDM和SM背景的$ H^+H^ - $生产的信号进行分析，并在运动学变量中选择了优化的选择条件，以最大程度地提高信号意义。将信号与背景进行比较，我们获得了可以在未来的$γγ$碰撞器实验中检测到的参数点。
The Inert Doublet Model(IDM) is one of the simplest extensions beyond Standard Model(SM) with an extended scalar sector, which provide a scalar dark matter particle candidate. In this paper, we investigate the double charged Higgs production at $γγ$ collider. By scanning the whole parameter space, we obtain the parameter points corresponding to the correct relic abundance of dark matter. After applying all theoretical and experimental constraints, the parameter space for the existence of dark matter is extremely restricted. We perform the analysis for the signal of $H^+H^-$ production in the IDM and the SM backgrounds, and the optimized selection conditions are chosen in kinematic variables to maximize signal significance. Comparing signal with backgrounds, we obtain the parameter points which can be detected at future $γγ$ collider experiments.
