Description
We show that in a class of two Higgs doublet model, where one Higgs doublet
generates masses of quarks and charged leptons whereas the other Higgs doublet with a tiny vacuum expectation value generates neutrino Dirac masses.
Thermal leptogenesis suitably works at low energy scale.
Its supersymmetric generalization also will be discussed.
