摘要:

惰性双态模型(IDM)是对标准模型(SM)的最简单的扩展,扩展了标量扇区,提供了一个标量暗物质粒子候选者。本文研究了在$γγ$对撞机上双电荷Higgs粒子的产生。通过扫描整个参数空间,我们得到了与正确的暗物质遗迹丰度相对应的参数点。在应用了所有的理论和实验限制之后,暗物质存在的参数空间受到了极大的限制。我们对IDM和SM背景下$H^+H^-$产生的信号进行了分析,并在运动学变量中选择了优化的选择条件以最大化信号显著性。通过信号与背景的比较,我们得到了在未来的$γγ$对撞机实验中可以检测到的参数点。

英文摘要:

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.
