Connection between some nonperturbative approaches in QCD

TL;DR

This paper explores the relationship between two nonperturbative QCD methods, revealing their shared feature of two condensates essential for confinement, thus unifying different theoretical approaches.

Contribution

It demonstrates a close connection between collective coordinate and spin-charge separation methods in nonperturbative QCD, highlighting the role of condensates in confinement.

Findings

Both approaches involve two condensates critical for confinement.

The approaches are shown to be interconnected.

Condensates serve as a unifying feature in nonperturbative QCD.

Abstract

The connection between two nonperturbative approaches in quantum chromodynamics is considered. The first one is based on a collective coordinate method, the second one on a spin-charge separation. It is shown that both approaches have some close connection: the existence of two condensates which are necessary to confinement.
