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…

Leading two-loop corrections to the Higgs di-photon decay in the Inert Doublet Model
Masashi Aiko, Johannes Braathen, Shinya Kanemura
Leading two-loop contributions to the di-photon decay of the Higgs boson are evaluated for the first time in the Inert Doublet Model (IDM). We employ for this calculation the Higgs…

Electroweak baryogenesis in 2HDM without EDM cancellation
Masashi Aiko, Motoi Endo, Shinya Kanemura +1
We study two Higgs doublet models with successful electroweak baryogenesis but without cancellations of electric dipole moments (EDMs). For the baryogenesis, additional scalar boso…
