Analysis of Spontaneous Mass Generation by Iterative Method in the Nambu-Jona-Lasinio Model and Gauge Theories

TL;DR

This paper introduces a new iterative approach to directly compute spontaneous mass generation resulting from dynamical chiral symmetry breaking in gauge theories, providing a definitive physical mass without auxiliary methods.

Contribution

The paper presents a novel iterative method for calculating spontaneous mass generation, avoiding reliance on free energy comparisons or other indirect techniques.

Findings

Successfully calculates physical mass directly

Eliminates need for free energy comparison

Applicable to gauge theories with chiral symmetry breaking

Abstract

We propose a new iterative method to directly calculate the spontaneous mass generation due to the dynamical chiral symmetry breaking. We can conclude the physical mass definitely without recourse to any other consideration like the free energy comparison.
