Description

Following a discussion on $W$-boson mass observed at the CDF and ATLAS, we explore the parameter space allowed in 2HDM+$S$ model. Further the model parameter space are constrained through vector-like leptons via muon g-2 dataset. We show our results for additional scalar mass fixed to $m_S \approx 96$ 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.
