Type-I Seesaw as the Common Origin of Neutrino Mass, Baryon Asymmetry, and the Electroweak Scale

Understand

The type-I seesaw represents one of the most popular extensions of the Standard Model.

• Previous studies of this model have mostly focused on its ability to explain neutrino oscillations as well as on the generation of the baryon asymmetry via leptogenesis.
• Recently, it has been pointed out that the type-I seesaw can also account for the origin of the electroweak scale due to heavy-neutrino threshold corrections to the Higgs potential.
• In this paper, we show for the first time that all of these features of the type-I seesaw are compatible with each other.
