1. Probing CP-violating Higgs sectors via the precision measurement of coupling constants / Aoki, Mayumi ; Hashino, Katsuya ; Kaneko, Daiki ; Kanemura, Shinya ; et al
We study how the effects of the CP violation can be observed indirectly by precision measurements of Higgs boson couplings at a future Higgs factory such as the International Linear Collider. [...]

6. Loop effects on the Higgs decay widths in extended Higgs models / Kanemura, Shinya ; Kikuchi, Mariko ; Mawatari, Kentarou ; Sakurai, Kodai ; et al
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 and gauge-boson pairs with one-loop electroweak and one-loop QCD corrections in various extended Higgs models, such as the Higgs singlet model and four types of two Higgs doublet models.

8. LHC 750 GeV diphoton excess in a radiative seesaw model / Kanemura, Shinya ; Nishiwaki, Kenji ; Okada, Hiroshi ; Orikasa, Yuta ; et al
We investigate a possibility for explaining the recently announced 750 GeV diphoton excess by the ATLAS and CMS experiments at the CERN LHC in a model with multiple doubly charged particles, that was originally suggested for explaining tiny neutrino masses through a three-loop effect in a natural way.
