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…
