Examining the neutrino option

TL;DR

The paper investigates the neutrino option, a scenario linking electroweak scale generation with neutrino masses via the seesaw mechanism, by analyzing loop corrections, data consistency, and UV completions.

Contribution

It systematically computes one-loop corrections, performs numerical consistency checks with data, and explores embedding into UV-complete models for the neutrino option.

Findings

Neutrino option remains viable for explaining particle masses.

Loop corrections are significant for precise matching.

Embedding into UV models is feasible.

Abstract

The neutrino option is a scenario where the electroweak scale, and thereby the Higgs mass, is generated simultaneously with neutrino masses in the seesaw model. This occurs via the leading one loop and tree level diagrams matching the seesaw model onto the Standard Model Effective Field Theory. We advance the study of this scenario by determining one loop corrections to the leading order matching results systematically, performing a detailed numerical analysis of the consistency of this approach with Neutrino data and the Standard Model particle masses, and by examining the embedding of this scenario into a more ultraviolet complete model. We find that the neutrino option remains a viable and intriguing scenario to explain the origin of observed particle masses.
