论文摘要
在这项工作中，我们比较了当前的2hdm $+$ scalar和伪卡尔的实验性LHC限制，用于$ t \ bar {t} $，mono- $ z $和mono- $ h $ signatures，并预测了mono-$ z $ cannel的未来LHC升级。此外，我们评论有信号检测的可能性，以区分这两个模型。 2HDM+S和2HDM+PS是所谓的下一代暗物质简化模型的两个值得注意的例子。它们通过后者与标量或伪科斯卡尔式单曲的混合，可以将费尔米金，标准模型单元，暗物质与两个Higgs Doublet扇形进行重纹率耦合。
In this work we compare the current experimental LHC limits of the 2HDM $+$ scalar and pseudoscalar for the $t \bar{t}$, mono-$Z$ and mono-$h$ signatures and forecast the reach of future LHC upgrades for the mono-$Z$ channel. Furthermore, we comment on the possibility, in case of a signal detection, to discriminate between the two models. The 2HDM+S and 2HDM+PS are two notable examples of the so-called next generation of Dark Matter Simplified Models. They allow for a renormalizable coupling of fermionic, Standard Model singlet, Dark Matter with a two Higgs doublet sector, through the mixing of the latter with a scalar or pseudoscalar singlet.
