In this talk, we discuss two Higgs doublet models in which a new U(1) gauge symmetry is introduced. We investigate if these models are allowed by current phenomenological data without introducing a scalar field except for two Higgs doublet ones. We find they are excluded by constraints from scalar boson decays associated with new gauge boson Z'. Then a dark vector-like fermion is introduced to...

The complex Higgs triplet model (CHTM) can explain the neutrino masses via the Type II seesaw mechanism. A feature of CHTM is that the electroweak rho parameter (\rho) deviates from unity at the tree-level. Thereby, how one renormalize electroweak sector is different from models with \rho=1. In this talk, we discuss imact of the radiative corrections to the 125 GeV Higgs boson decays in CHTM....

Spontaneous CP-violation (SCPV) is one of the interesting possibilities for explaining observed CP-violation. As a simple realization of SCPV, we consider 2 Higgs doublet models (2HDMs), where complex phases of the Higgs doublets can be a source of SCPV. We discuss two important phenomenological consequences of the SCPV 2HDMs,

The compressed mass spectrum of the electroweak inert scalar models pose a significant challenge for current collider experiments, as the soft visible decay products and suppressed production rates hinder conventional search strategies. In this talk, I will explore the discovery prospects of such a compressed electroweak sector at a future high energy Muon Collider operating at 10 TeV....
