Observable T_7 Lepton Flavor Symmetry at the Large Hadron Collider

TL;DR

This paper presents a simple, renormalizable neutrino mass model using T_7 symmetry and B-L gauging, which predicts observable signatures at the Large Hadron Collider, differing from typical models relying on nonrenormalizable operators.

Contribution

It introduces a minimal, renormalizable neutrino mass model with T_7 symmetry and B-L gauging, eliminating the need for auxiliary symmetries and flavons.

Findings

Model predicts observable signatures at the LHC.

Achieves tribimaximal mixing without nonrenormalizable operators.

Simplifies flavor symmetry models with fewer assumptions.

Abstract

More often than not, models of flavor symmetry rely on the use of nonrenormalizable operators (in the guise of flavons) to accomplish the phenomenologically successful tribimaximal mixing of neutrinos. We show instead how a simple renormalizable two-parameter neutrino mass model of tribimaximal mixing can be constructed with the non-Abelian discrete symmetry T_7 and the gauging of B-L. This is also achieved without the addition of auxiliary symmetries and particles present in almost all other proposals. Most importantly, it is verifiable at the Large Hadron Collider.
