N2 - We consider an extension of the Standard Model by heavy right-handed neutrinos and heavy Higgs doublets and show, using a renormalization group approach, that this model can simultaneously provide an explanation for the small neutrino masses and for the mild hierarchy observed between the atmospheric and the solar mass splittings, even when the extra degrees of freedom are very heavy. We analyse the necessary conditions to reproduce the oscillation parameters and we discuss possible experimental signatures of this model.
