Scale invariant radiative neutrino mass model
Daijiro Suematsu
We propose a scale invariant radiative neutrino mass model with custodial symmetry by introducing two real singlet scalars to the scotogenic model. Masses of an inert doublet scala…
Right-handed neutrino dark matter consistent with the generation of baryon number asymmetry
Daijiro Suematsu
A right-handed neutrino is a promising candidate for dark matter (DM) which has no interaction with nuclei. Since two right-handed neutrinos explain neutrino oscillation data and b…
Neutrino models with a zero mass eigenvalue
Daijiro Suematsu
Absolute values of the neutrino mass are not known still now although their upper bounds are constrained through several experiments and observations. Recent analyses of cosmologic…
Right-handed neutrino as a common progenitor of baryon number asymmetry and dark matter
Daijiro Suematsu
Cosmological and astrophysical observations suggest that both energy densities of baryon and dark matter take the same order values in the present Universe. We propose a scenario t…
issues in the SM from a view point of spontaneous violation
Daijiro Suematsu
The standard model (SM) has several issues related to the violation which could give clues to search physics beyond the SM. They are a phase in the CKM matrix, the strong…
Inflation caused by a potential valley with CP violation
Daijiro Suematsu
We propose an inflation scenario caused by an inflaton identified with a potential valley which brings about violation in the standard model (SM). If singlet scalars have nonm…
