The Nambu-Jona Lasinio mechanism and the electroweak symmetry breaking in the Standard Model

TL;DR

This paper explores how the Nambu-Jona Lasinio (NJL) mechanism can be applied to the Standard Model to explain electroweak symmetry breaking dynamically, offering an alternative perspective to the traditional Higgs mechanism.

Contribution

It demonstrates a self-consistent realization of electroweak symmetry breaking using the NJL mechanism within an electroweak invariant Lagrangian, providing a different dynamical approach.

Findings

Reproduces the electroweak symmetry breaking dynamically

Shows the NJL mechanism can be integrated into the Standard Model

Offers insights into the hidden dynamical content of Green functions

Abstract

This is a short report of the entire work developed during the study of the possible realizations of the "Top Mode" Standard Model. Here it is examined the breaking of internal symmetries from another point of view showing that is possible to reproduce the gauged electroweak panorama of the traditional Standard Model in a exhaustive and selfconsistent way. The result is reached applying the main futures of the Nambu-Jona Lasinio (NJL) mechanism to an electroweak invariant Lagrangian. In this context the use of functional formalism for composite operators naturally leads to a different dynamical approach. Meanwhile the Higgs mechanism acts on the Lagrangian form, a NJL like model looks directly at the physics of the system showing the real dynamical content hidden in the Green functions of the theory.
