Discriminating the minimal 3-3-1 models

TL;DR

This paper evaluates minimal 3-3-1 models, demonstrating that theoretical and experimental constraints severely limit their viability and gauge symmetry breaking scales.

Contribution

It provides a comprehensive analysis of constraints on minimal 3-3-1 models, showing their limitations due to ho parameter, Landau pole, and FCNCs bounds.

Findings

Reduced 3-3-1 model is unrealistic due to ho parameter and Landau pole.

Simple 3-3-1 model is experimentally unfavored because of ho parameter and FCNCs.

Constraints strictly limit the gauge symmetry breaking scales.

Abstract

We show that due to the \rho parameter bound and the Landau pole limit, the reduced 3-3-1 model is unrealistic, while due to the \rho parameter and FCNCs bounds, the simple 3-3-1 model is experimentally unfavored. All such conditions strictly constrain the gauge symmetry breaking scales of the minimal 3-3-1 model with three scalar triplets.
