论文摘要

两个Higgs Doublet模型与标准模型偶联,并与新的稳定,中性粒子耦合,提供了一种吸引人且相当最小的途径,以解决暗物质问题。他们已经是LHC进行了几次搜索的主题。我们研究了现有的LHC测量对此类模型的影响,首先是通过搜索来解决的基准区域,然后在放宽了一些假设并扩大所考虑的参数范围之后。在每种情况下,我们都会研究新参数如何改变LHC处的潜在可见签名,并确定这些签名中的哪些已经对现有测量结果产生了重大影响。这使我们能够对迄今未研究的许多情况设置一些第一个约束。

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.
