Canonical Seesaw Mechanism in Electro-Weak SU(4)L x U(1)Y Models

TL;DR

This paper demonstrates how the canonical seesaw mechanism can be integrated into SU(4)L x U(1)Y gauge models, naturally generating neutrino masses while preserving Standard Model phenomenology.

Contribution

It shows the natural implementation of the seesaw mechanism in a specific class of high-symmetry gauge models using an algebraic approach.

Findings

Neutrino mass spectrum depends on a single free parameter 'a'.

Standard Model phenomenology remains unaffected.

High-scale new physics at ~10^11 GeV.

Abstract

In this paper we prove that the canonical seesaw mechanism can naturally be implemented in a particular class of electro-weak SU(4)L x U(1)Y gauge models. The resulting neutrino mass spectrum is determined by just tuning a unique free parameter 'a' within the algebraical method of solving gauge models with high symmetries. All the Standard Model phenomenology is preserved, being unaffected by the new physics occuring at a high breaking scale m ~ 10^11GeV.
