No-go limitations on UV completions of the neutrino option

We discuss the possible origin of the Majorana mass scale(s) required for the neutrino option where the electroweak scale is generated simultaneously with light neutrino masses in a type-I seesaw model by common dimension four interactions. We establish no-go constraints on the perturbative generation of the Majorana masses required due to global symmetries of the seesaw Lagrangian.

Automated summary

In this discussion, the potential origins of Majorana mass scales required for the neutrino option are explored, particularly in a type-I seesaw model where the electroweak scale is generated simultaneously with light neutrino masses through common dimension four interactions. Constraints are established on the perturbative generation of these Majorana masses, driven by the global symmetries of the seesaw Lagrangian.
