Small neutrino masses from a decoupled singlet scalar field
We propose a unified solution with Z4 discrete symmetry for small neutrino masses and stability of dark matter. The Standard Model is extended with an inert doublet scalar, a dark singlet scalar, a spurion scalar and right-handed neutrinos, which all transform nontrivially under Z4. After the Z4 sym...
