Non-Abelian Discrete Flavor Symmetries

TL;DR

This paper surveys non-Abelian discrete flavor symmetries used in particle physics to explain lepton and quark flavor structures, discussing their implications and potential experimental signatures at the LHC.

Contribution

It provides an overview of various non-Abelian discrete symmetries and their role in modeling flavor physics, highlighting the connection to scalar particles and collider prospects.

Findings

Some models predict very massive scalars with limited collider signatures.

Other models suggest scalars at the TeV scale accessible at the LHC.

The survey emphasizes the experimental testability of certain flavor symmetry models.

Abstract

This is an incomplete survey of some non-Abelian discrete symmetries which have been used recently in attempts to understand the flavor structure of leptons and quarks. To support such symmetries, new scalar particles are required. In some models, they are very massive, in which case there may not be much of a trace of their existence at the TeV scale. In other models, they are themselves at the TeV scale, in which case there is a reasonable chance for them to be revealed at the LHC (Large Hadron Collider) at CERN.
