Two Higgs doublet models with an additional pseudoscalar particle coupling to the Standard Model and to a new stable, neutral particle, provide an attractive and fairly minimal route to solving the problem of Dark Matter. They have been the subject of several searches at the LHC. We study the impact of existing LHC measurements on such models, first in the benchmark regions addressed by searches and then after relaxing some of their assumptions and broadening the parameter ranges considered. In each case we study how the new parameters change the potentially visible signatures at the LHC, and identify which of these signatures should already have had a significant impact on existing measurements. This allows us to set some first constraints on a number of so far unstudied scenarios.

用伪标量调解器对暗物质研究两个希格斯双峰模型的对撞机签名

两个希格斯双峰模型以及与标准模型和新的稳定中性粒子耦合的额外伪标量粒子，为解决暗物质问题提供了一种有吸引力且相当少的途径。他们一直是大型强子对撞机搜索的主题。我们首先在搜索解决的基准区域中研究现有LHC测量对此类模型的影响，然后放宽它们的某些假设并扩大所考虑的参数范围，然后对其进行研究。在每种情况下，我们都研究新参数如何改变大型强子对撞机的潜在可见特征，并确定其中哪些特征应已对现有测量产生重大影响。这使我们可以对许多迄今尚未研究的场景设置一些首要约束。
