Conformal Realization of the Neutrino Option

Understand

It was recently proposed that the electroweak hierarchy problem is absent if the generation of the Higgs potential stems exclusively from quantum effects of heavy right-handed neutrinos which can also generate active neutrino masses via the type-I seesaw mechanism.

• Hence, in this framework dubbed the "neutrino option", the tree-level scalar potential is assumed to vanish at high energies.
• Such a scenario therefore lends itself particularly well to be embedded in a classically scale-invariant theory.
• In this paper we perform a survey of models featuring conformal symmetry at the high scale.
