A bstract We present a comprehensive study on Higgs pair production in various
archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet …

We investigate production of primordial black holes from first-order electroweak phase
transition in the framework of the nearly aligned Higgs effective field theory, in which non …

The trilinear Higgs coupling λ hhh is crucial for determining the structure of the Higgs
potential and for probing possible effects of physics beyond the standard model. Focusing …

We investigate predictions on the triple Higgs boson couplings with radiative corrections in
the model with an additional real singlet scalar field. In this model, the second physical …

We investigate the possible size of two-loop radiative corrections to the Higgs trilinear
coupling λ hhh in two types of models with extended Higgs sectors, namely in a Two-Higgs …

In this study of the Inert Doublet Model (IDM), we propose that the dijet+ missing transverse
energy channel at the Large Hadron Collider (LHC) will be an effective way of searching for …

We discuss a possibility that the parameter space of the two Higgs doublet model is
significantly narrowed down by considering the synergy between direct searches for …

We compute the dominant two-loop corrections to the Higgs trilinear coupling λ _ hhh λ hhh
and to the Higgs quartic coupling λ _ hhhh λ hhhh in models with extended Higgs sectors …

We consider an extension of the standard model (SM) with an inert Higgs doublet and three
Majorana singlet fermions to address both origin and the smallness of neutrino masses and …

Abstract The nearly aligned Higgs Effective Field Theory (naHEFT) is based on the general
assumption: all deviations in the Higgs boson couplings are originated from quantum one …
