Stabilization of the Electroweak Scale in 3-3-1 Models

TL;DR

This paper discusses how certain 3-3-1 models with a Landau pole at TeV scale naturally stabilize the electroweak scale through nonperturbative dynamics, eliminating the need for additional protection mechanisms.

Contribution

It introduces a mechanism within 3-3-1 models where nonperturbative effects at TeV scale stabilize the electroweak scale, avoiding hierarchy problem issues.

Findings

Nonperturbative dynamics arise at TeV scale in 3-3-1 models.

Electroweak scale stabilization without fine-tuning.

Landau pole at TeV scale acts as a natural cutoff.

Abstract

One way of avoiding the destabilization of the electroweak scale through a strong coupled regime naturally occurs in models with a Landau-like pole at the TeV scale. Hence, the quadratic divergence contributions to the scalar masses are not considered as a problem anymore since a new nonperturbative dynamic emerges at the TeV scale. This scale should be an intrinsic feature of the models and there is no need to invoke any other sort of protection for the electroweak scale. In some models based on the $SU(3)_C\otimes SU(3)_W\otimes U(1)_{X}$ gauge symmetry, a nonperturbative dynamics arise and it stabilizes the electroweak scale.
