LHC 750 GeV Diphoton excess in a radiative seesaw model
Shinya Kanemura, Kenji Nishiwaki, Hiroshi Okada +3
We investigate a possibility for explaining the recently announced 750\,GeV diphoton excess by the ATLAS and the CMS experiments at the CERN LHC in a model with multiple doubly cha…
Probing Models of Neutrino Masses via the Flavor Structure of the Mass Matrix
Shinya Kanemura, Hiroaki Sugiyama
We discuss what kinds of combinations of Yukawa interactions can generate the Majorana neutrino mass matrix. We concentrate on the flavor structure of the neutrino mass matrix beca…
Radiative corrections to the Higgs boson couplings in the model with an additional real singlet scalar field
Shinya Kanemura, Mariko Kikuchi, Kei Yagyu
We calculate renormalized Higgs boson couplings with gauge bosons and fermions at the one-loop level in the model with an additional isospin singlet real scalar field. These coupli…
Phenomenology of the Georgi-Machacek model at future electron-positron colliders
Cheng-Wei Chiang, Shinya Kanemura, Kei Yagyu
We study the phenomenology of the exotic Higgs bosons in the Georgi-Machacek model at future electron-positron colliders such as the International Linear Collider (ILC), assuming t…
Gravitational waves as a probe of extended scalar sectors with the first order electroweak phase transition
Mitsuru Kakizaki, Shinya Kanemura, Toshinori Matsui
We discuss spectra of gravitational waves which are originated by the strongly first order phase transition at the electroweak symmetry breaking, which is required for a successful…
Unitarity bound in the most general two Higgs doublet model
Shinya Kanemura, Kei Yagyu
We investigate unitarity bounds in the most general two Higgs doublet model without a discrete symmetry nor CP conservation. S-wave amplitudes for two-body elastic scattering…
