Radiative neutrino mass model with degenerate right-handed neutrinos
Shoichi Kashiwase, Daijiro Suematsu
The radiative neutrino mass model can relate neutrino masses and dark matter at a TeV scale. If we apply this model to thermal leptogenesis, we need to consider resonant leptogenes…
Inflation due to a non-minimal coupling of singlet scalars in the radiative seesaw model
Romy H. S. Budhi, Shoichi Kashiwase, Daijiro Suematsu
The radiative neutrino mass model with inert doublet dark matter is a promising model for the present experimental issues which cannot be explained within the standard model. We st…
Lepton number asymmetry via inflaton decay in a modified radiative seesaw model
Shoichi Kashiwase, Daijiro Suematsu
We propose a non-thermal scenario for the generation of baryon number asymmetry in a radiative neutrino mass model which is modified to realize inflation at the early Universe. In…
Constrained inflaton due to a complex scalar
Romy H. S. Budhi, Shoichi Kashiwase, Daijiro Suematsu
We reexamine inflation due to a constrained inflaton in the model of a complex scalar. Inflaton evolves along a spiral-like valley of special scalar potential in the scalar field s…
Two Loop Neutrino Model with Dark Matter and Leptogenesis
Shoichi Kashiwase, Hiroshi Okada, Yuta Orikasa +1
We study a two-loop induced radiative neutrino model at TeV scale with global symmetry, in which we analyze dark matter and resonant leptogenesis. The model includes two kin…
Inflation in a modified radiative seesaw model
Shoichi Kashiwase
A radiative seesaw model with an inert doublet dark matter is a promising candidate which could explain the existence of neutrino masses, dark matter and baryon number asymmetry of…
