We briefly survey several typical CP-conserving two-Higgs-doublet models (2HDMs) in light
of current experiments. First we derive the masses and couplings of the mass eigenstates …

The existence of charged Higgs boson (s) is inevitable in models with two (or more) Higgs
doublets. Hence, their discovery would constitute unambiguous evidence for new physics …

A bstract We study the stability of neutral electroweak vacua in two Higgs doublet models,
and calculate the lifetime of these states when the parameters are such that they are false …

We point out the importance of the decay channels A→ Z h and H→ VV in the wrong-sign
limit of the two-Higgs-doublet model (2HDM) of type II. They can be the dominant decay …

We study two novel aspects of democratic three-Higgs-doublet models (3HDMs)—the
custodial limit and the possibility of wrong-sign Yukawa couplings. In the custodial limit, the …

We study the kinematic characteristics of the loop-induced effects on nonresonant Higgs pair
production via gluon fusion in a type-II two Higgs doublet model with heavy vectorlike …

Contrary to common perception, we show that the current Higgs data does not eliminate the
possibility of a sequential fourth generation that get their masses through the same Higgs …

In light of the recently obtained LHC Higgs data, we examine the parameter space of the
type II two-Higgs-doublet model, in which the 125 GeV Higgs bosons exhibit wrong sign …

In the framework of the type-II two-Higgs-doublet model with a scalar dark matter (S), we
examine the wrong sign Yukawa coupling of the 125 GeV Higgs, which is the only portal …

A bstract We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered
Higgs boson in the Yukawa-aligned two Higgs doublet model. In the WS scenario, Yukawa …
