Radiative Symmetry Breaking with a Scale Invariant Seesaw

We study a scale invariant inverse seesaw model that radiatively generates the electroweak scale, the Standard Model (SM) neutrino masses, and stabilizes the electroweak vacuum. Previous studies have noted that the SM Higgs potential and the electroweak scale can be radiatively generated via the minimal seesaw mechanism. This scenario, called the ``Neutrino Option'', was UV-completed by a scale invariant framework. However, these models predict singlet neutrino and scalar masses at $10^7-10^9$ GeV, beyond any experimental reach and leave the electroweak vacuum meta/un-stable at high energies. In this work, we propose modifications to this framework that lower the singlet neutrino masses to experimentally accessible scales through an inverse seesaw mechanism, while fully stabilizing the electroweak vacuum with an additional singlet scalar. The possibility of generating the observed baryon asymmetry of the universe via leptogenesis is also explored.
