在$\texttt{GAMBIT}$中使用全局拟合探索2HDM
Exploring the 2HDM with Global Fits in $\texttt{GAMBIT}$
摘要:
在这项工作中,我们提出了一个全球性的第二型两希格斯偶极子模型(2HDM)的工具$\texttt{GAMBIT}$的初步结果。我们的研究包括各种约束,包括理论约束(么正性,微扰性和真空稳定性),希格斯粒子在对撞机上的搜索,电弱物理和风味约束。最新的实验结果不仅证实了以往的研究,而且进一步探索了模型。我们发现,例如,$B\rightarrow K^*μ^+μ^-$角可观测量不能解释在类型II 2HDM。
英文摘要:
In this work, we present preliminary results of a global fit of the type-II two-Higgs-doublet model (2HDM) with the tool $\texttt{GAMBIT}$. Our study includes various constraints, including the theoretical constraints (unitarity, perturbativity and vacuum stability), Higgs searches at colliders, electroweak physics and flavour constraints. With the latest experimental results, our results not only confirm past studies but also go further in probing the model. We find, for example, that the measurements of $B\rightarrow K^*μ^+μ^-$ angular observables cannot be explained in the type-II 2HDM.
