Abstract Models with non-minimal Higgs sectors represent a mainstream direction in
theoretical exploration of physics opportunities beyond the Standard Model. Extended scalar …

A comprehensive review of physics at an e^+ e^-e+ e-linear collider in the energy range of
s= 92 s= 92 GeV–3 TeV is presented in view of recent and expected LHC results …

In this article, we revisit the Type II seesaw mechanism based on the addition of a weak
triplet scalar to the standard model. We perform a comprehensive study of its …

An evidence for a diphoton resonance at a mass of 750 GeV has been observed in the data
collected at the LHC run at a center of mass energy of 13 TeV. We explore several …

We calculate the Higgs decay rate of h→ Z γ by including the contributions from new scalars
with arbitrary quantum numbers of the weak isospin (T) and hypercharge (Y) in the Standard …

We calculate radiative corrections to a full set of coupling constants for the 125 GeV Higgs
boson at the one-loop level in two Higgs doublet models with four types of Yukawa …

After the discovery of the standard model-like Higgs boson at the LHC, the structure of the
Higgs sector remains unknown. We discuss how it can be determined by the combination of …

A bstract We study constraints from perturbativity and vacuum stability as well as the EWPD
in the type II seesaw model. As a result, we can put stringent limits on the Higgs triplet …

A bstract We study the vacuum stability and unitarity conditions for a 125 GeV Standard
Model (SM)-like Higgs boson mass in the type-II seesaw model. We find that, as long as the …

The type II seesaw model is a well-motivated new physics scenario to address the origin of
the neutrino mass issue. We show that this model can easily accommodate an absolutely …
