Exploring the 2HDM with Global Fits in $\text{GAMBIT}$

Abstract

In this work, we present preliminary results of a global fit of the type-II two-Higgs-doublet model (2HDM) with the tool $\text{GAMBIT}$. 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 $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$ angular observables cannot be explained in the type-II 2HDM.
