Radiative corrections to decays of the 125 GeV Higgs boson in the complex Higgs triplet model
Masashi Aiko, Shinya Kanemura, Mariko Kikuchi +3
The extension of the Higgs sector with an additional complex triplet field is often considered for generating the neutrino mass by the Type-II seesaw mechanism. Such an extension g…
Probing Spontaneous CP-Violation through Precision Higgs Observables
Tanmoy Mondal, Kei Yagyu
We investigate the implications of spontaneous CP-violation in the general two Higgs doublet model, which leads to a non-decoupling structure of the Higgs sector. All the masses of…
New renormalization scheme in extended Higgs sectors for Higgs precision measurements
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu
We discuss a new renormalization scheme for mixing angles in extended Higgs sectors for the coming era of the Higgs precise measurements at future lepton colliders. We focus on the…
New renormalization scheme in the two Higgs doublet models
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu
We propose a new renormalization scheme in the two Higgs doublet models with a softly-broken symmetry and CP-conservation in the Higgs sector. In this scheme, counterterms fo…
H-COUP Version 3: A program for one-loop corrected decays of any Higgs bosons in non-minimal Higgs models
Masashi Aiko, Shinya Kanemura, Mariko Kikuchi +2
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 Higgs sector…
