Dilaton as the Higgs boson

TL;DR

This paper proposes a model where the dilaton acts as the Higgs boson, demonstrating that gauge invariance violations are fictitious and resulting in an effective theory similar to the top mode standard model.

Contribution

It introduces a dilaton-based Higgs model with gauge invariance violations shown to be fictitious, aligning with the top mode standard model at low energies.

Findings

Gauge invariance violations are fictitious.

The model reproduces the top mode standard model at low energies.

The dilaton can effectively replace the Higgs boson in electroweak symmetry breaking.

Abstract

We propose a model where the role of the electroweak Higgs field is played by the dilaton. The model contains terms which explicitly violate gauge invariance, however it is shown that this violation is fictitious, so that the model is a consistent low energy effective theory. In the simplest version of the idea the resulting low energy effective theory is the same as the top mode standard model.
