Comment on `A simple explanation of the non-appearance of physical gluons and quarks'

TL;DR

This paper critiques a recent claim that non-appearance of physical gluons and quarks is automatic in QCD, providing counterarguments to challenge the original assertion.

Contribution

It offers a critical analysis and refutes the claim that non-abelian color interactions automatically exclude physical gluons and quarks.

Findings

Counterarguments undermine the claim of automatic non-appearance

Highlights the need for more detailed explanations in QCD

Questions simplified explanations of confinement mechanisms

Abstract

In a recent paper by Johan Hansson [hep-ph/0208137] it is claimed that the non-appearance of quarks and gluons as physical particles is an automatic result of the nonabelian nature of the color interaction in quantum chromodynamics. It is shown that the arguments given by Hansson are insufficient to support his claim by giving simple counter arguments.
