The vacuum nature of the QCD condensates

TL;DR

This paper argues that QCD condensates are intrinsic vacuum properties rather than confined within hadrons, challenging recent claims and supporting the traditional view with model calculations.

Contribution

It refutes the in-hadron interpretation of QCD condensates and explicitly demonstrates their vacuum nature through a model calculation.

Findings

QCD condensates are vacuum properties, not confined within hadrons.

The in-hadron picture conflicts with established concepts and experimental data.

Model calculations support the vacuum nature of the quark condensate.

Abstract

Recently it was claimed that QCD condensates were associated with the internal dynamics of the hadrons. We challenge this "in-hadron" picture of the QCD condensates and show that it conflicts well established concepts and experimental facts for the example of the quark condensate. We explicitly demonstrate the vacuum nature of the quark condensate by a model calculation.
