Double Higgs boson production at colliders in the two-Higgs-doublet model
Tadashi Kon, Takuto Nagura, Takahiro Ueda +1
We study the double Higgs boson production processes () with being the 125 GeV Higgs boson in the two-Higgs-doublet model with a softly-broken…
A Concrete Composite 2-Higgs Doublet Model
Stefania De Curtis, Luigi Delle Rose, Stefano Moretti +1
We consider a Composite Higgs Model (CHM) with two isospin doublet Higgs fields arising as pseudo Nambu-Goldstone bosons from a break…
Models with higher weak-isospin Higgs multiplets
Cheng-Wei Chiang, Kei Yagyu
In order for scale factors of the 125-GeV Higgs boson couplings to have the possibilities of being greater than unity and while keeping…
One-loop renormalized Higgs vertices in Georgi-Machacek model
Cheng-Wei Chiang, An-Li Kuo, Kei Yagyu
We compute renormalized vertices of the 125 GeV Higgs boson with the weak gauge bosons (), fermions () and itself () in the Georgi-Machacek model at one-lo…
Supersymmetry versus Compositeness: 2HDMs tell the story
Stefania De Curtis, Luigi Delle Rose, Stefano Moretti +1
Supersymmetry and Compositeness are two prevalent paradigms providing both a solution to the hierarchy problem and a motivation for a light Higgs boson state. As the latter has now…
Loop effects on the Higgs decay widths in extended Higgs models
Shinya Kanemura, Mariko Kikuchi, Kentarou Mawatari +2
In order to identify the Higgs sector using future precision data, we calculate the partial decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs a…
