摘要

用复标量单重态（2HDMS）增强的双希格斯-双重态模型是超越标准模型（BSM）物理学的一个很好的候选者。我们以复标量单重态作为暗物质候选者，研究了2HDMS的暗物质现象学。我们对现有的理论和实验限制所允许的参数空间进行了研究，这些限制来自暗物质、风味物理和对撞机搜索。此外，我们讨论了一些基准情景，以测试在HL-LHC和未来的高能\(e^+e^-\)对撞机上发现2HDMS的潜力。

Phenomenology of the dark matter sector in the 2HDM extended with complex scalar singlet

The two-Higgs-doublet model augmented with a complex scalar singlet (2HDMS) is a well-motivated candidate for Beyond Standard Model (BSM) Physics. We investigate the dark matter phenomenology of the 2HDMS with the complex scalar singlet as the dark matter candidate. We perform a study of the parameter space allowed by existing theoretical and experimental constraints from dark matter, flavour physics and collider searches. Further, we discuss a few benchmark scenarios to test the discovery potential for the 2HDMS at the HL-LHC and at future high-energy \(e^+e^-\) colliders.
