Leptogenesis in a TeV scale neutrino mass model with inverted mass
hierarchy    [PDF]

Shoichi Kashiwase, Daijiro Suematsu

Realization of the inverted hierarchy is studied in the radiative neutrino mass model with an inert doublet, in which neutrino masses and dark matter could be induced from a common particle. We show that the sufficient baryon number asymmetry is generated through resonant leptogenesis even for the case with rather mild degeneracy among TeV scale right-handed neutrinos. We also discuss the relation between the baryon number asymmetry and low energy experiments for the DM direct search, the neutrinoless double beta decay and so on.
