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…
