在LHC比较2HDM $+$标量和伪标量简化模型

Comparing 2HDM $+$ Scalar and Pseudoscalar Simplified Models at LHC

Giorgio Arcadi, Giorgio Busoni, Thomas Hugle, Valentin Titus Tenorth

摘要:

在这项工作中,我们比较了当前实验的LHC限制的2HDM $+$标量和赝标量的$t \bar{t}$,单$Z$和单$h$签名和预测达到未来的LHC升级单$Z$通道。此外,我们评论的可能性,在信号检测的情况下,区分这两种模式。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。它们允许费米子、标准模型单线态、暗物质与两个希格斯双重态扇区的可重整化耦合,通过后者与标量或赝标量单线态的混合。

英文摘要:

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.
