“…In the inert 2HDM, the lightest neutral field of the inert doublet is stable and thus can serve as the DM candidate [171,172]. However, with various theoretical and experimental constraints, especially the DM direct detection limits, the parameter space for a correct relic density is highly restrained (for a recent study, see, e.g, [173]). A more promising scenario is the type-II 2HDM extended by introducing a real singlet scalar S under a Z 2 symmetry [174].…”

The Higgs boson may serve as a portal to new physics beyond the standard model (BSM), which is implied by the theoretical naturalness or experimental anomalies. This review aims to briefly survey some typical Higgs-related BSM models. First, for the theories to solve the hierarchy problem, the two exemplary theories, the low energy supersymmetry (focusing on the minimal supersymmetric model) and the little Higgs theory, are discussed. For the phenomenological models without addressing the hierarchy problem, we choose the two-Higgs-doublet models (2HDMs) to emphatically elucidate their phenomenological power in explaining current measurements of muon g−2, the W-boson mass and the dark matter (DM) data. For the singlet extensions, which are motivated by the cosmic phase transition and the DM issue, we illustrate the singlet-extended standard model (xSM) and the singlet-extended 2HDM (2HDM+S), emphasizing the vacuum stability. In the decade since the discovery of the Higgs boson, these theories have remained the typical candidates of new physics, which will be intensively studied in future theoretical and experimental research.
