Radiative Generation of the Lepton Mass
Hiroshi Okada, Kei Yagyu
We propose a new mechanism where both Dirac masses for the charged-leptons and Majorana masses for neutrinos are generated via quantum levels. The charged-lepton masses are given b…
ILC Higgs White Paper
D. M. Asner, T. Barklow, C. Calancha +20
The ILC Higgs White Paper is a review of Higgs Boson theory and experiment at the International Linear Collider (ILC). Theory topics include the Standard Model Higgs, the two-Higgs…
Electron/Muon Specific Two Higgs Doublet Model
Yuji Kajiyama, Hiroshi Okada, Kei Yagyu
We discuss two Higgs doublet models with a softly-broken discrete symmery, where the mass matrix for charged-leptons is predicted as the diagonal form in the weak ei…
Enhancements of weak gauge boson scattering processes at the CERN LHC
Cheng-Wei Chiang, An-Li Kuo, Kei Yagyu
Current CERN Large Hadron Collider data on the 126 GeV standard model-like Higgs boson suggest the possibility of larger Higgs boson couplings with the weak gauge bosons, …
Flavor Model in Three Loop Seesaw and Higgs Phenomenology
Yuji Kajiyama, Hiroshi Okada, Kei Yagyu
We propose a new type of radiative seesaw model in which observed neutrino masses are generated through a three-loop level diagram in combination with tree-level type-II seesaw mec…
First constraint on the mass of doubly-charged Higgs bosons in the same-sign diboson decay scenario at the LHC
Shinya Kanemura, Kei Yagyu, Hiroshi Yokoya
When the doubly-charged Higgs bosons mainly decay into the same-sign dilepton, a lower bound on the mass is around 400 GeV by the current LHC data. On the other hand,…
