Description

Under the assumption of hierarchical right-handed neutrino masses, masses of right-handed neutrinos must be larger than $10^8$ GeV in the standard thermal leptogenesis scenario. On the other hand, we show the mass can be reduced to around 5 TeV in a neutrinophilic two Higgs doublet model. We also show the required mass degeneracy for resonant leptogenesis scenario becomes rather mild in neutrinophilic two Higgs doublet model.
