    We consider the extension of the SM with an inert scalar doublet,
    three right-handed neutrinos, and singlet scalar fields, ϕ and S. In this model, neutrino
    masses are zero in the limit of the unbroken Z4 discrete symmetry. We show that when the
    singlet scalar field ϕ gets a VEV, the Z4 symmetry is broken to Z2, and neutrino masses
    are generated at one-loops due to the mixings between the...
