Constraining 2HDM+S model through W-boson mass measurements

arXiv:2312.08807

Abstract

Following a discussion on $W$ -boson mass observed at the CDF and ATLAS, we explore the parameter space allowed in the 2HDM+ $S$ model. Further, the model parameter space is constrained through vector-like leptons via muon $g - 2$ measurements. We show our results for additional scalar mass fixed to $m_{S} \approx 95$ and $150$ ~GeV keeping the standard Higgs-boson mass at 125~GeV in all four types of 2HDM+ $S$ model. The chosen mass of the singlet scalar is motivated by the excesses seen at the CMS and ATLAS data in proton-proton collisions at the Large Hadron Collider.
