# Effective locality and chiral symmetry breaking in QCD

## TL;DR

This paper explores how effective locality, a non-perturbative property of QCD's fermionic Green's functions, relates to dynamical chiral symmetry breaking under certain approximations.

## Contribution

It investigates the connection between effective locality and chiral symmetry breaking in QCD using eikonal and quenching approximations.

## Key findings

- Effective locality is linked to chiral symmetry breaking in QCD.
- The study provides insights into non-perturbative aspects of QCD.
- Results are obtained within specific approximation schemes.

## Abstract

A few years ago the use of standard functional manipulations was demonstrated to imply an unexpected property satisfied by the fermionic Green's functions of QCD, and called effective locality. This feature of QCD is non-perturbative as it results from a full integration of the gluonic degrees of freedom. In this paper, at eikonal and quenching approximation at least, the relation of effective locality to dynamical chiral symmetry breaking is examined.
