Description
The 2HDM+S is the singlet extension of the two-Higgs-doublet model (2HDM). The singlet field and its mixing with the 2HDM Higgs sector lead to new contributions to the electroweak precision observables, in particular, the oblique parameters, as well as the direct searches of BSM Higgs In this work we performed a systematic investigation of the impacts of each mixing angle on the oblique parameters. We identified five benchmark cases, where at most one mixing angle was nonzero, and analyzed the 95% C.L. allowed parameter space using the oblique parameters. We also studied the non-alignment limit of the 2HDM+S, which typically has tighter constraints on the masses and mixing angles. We will also show the results from LHC direct searches and compare the 2HDM+S and 2HDM.
