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 …

A bstract We discuss electroweak baryogenesis in aligned two Higgs doublet models. It is
known that in this model the severe constraint from the experimental results for the electron …

A bstract We present the results of a global fit to the Aligned Two-Higgs Doublet Model,
assuming that there are no new sources of CP violation beyond the quark mixing matrix. We …

We investigate the phenomenology of the dark Z boson, Z d, which is associated with a new
Abelian gauge symmetry and couples to the standard model particles via kinetic mixing ϵ …

We propose a novel signature with four-photon final states to probe CP-violating (CPV)
extended Higgs sectors via ff¯→ Z*→ H 1 H 2→ 4 γ processes with H 1, 2 being additional …

We consider two Higgs doublet models (THDMs) with both the Higgs potential and Yukawa
interactions being aligned, which we call “double-aligned THDMs.” In this scenario, coupling …

A bstract We present the first explicit calculation of leading two-loop corrections to the Higgs
trilinear coupling λ hhh in models with classical scale invariance (CSI), using the effective …

The H-COUP program is provided as a package of Fortran codes, which can compute
observables related to Higgs bosons including radiative corrections in various extended …

We investigate the impact of electroweak (EW), scalar and QCD corrections to the full set of
decay branching ratios of an additional CP-even Higgs boson (H) in the two Higgs doublet …

We discuss first-order electroweak phase transition in models with extended Higgs sectors
for the case with relatively heavy additional scalar bosons. We first show that, by the …
