TL;DR
This paper revisits the gluon chain model of QCD string formation, demonstrating its consistency with key features of confinement such as Casimir scaling, flux tube broadening, and the Luscher term.
Contribution
It provides a comprehensive analysis showing that the gluon chain model satisfies essential criteria for a confining force in QCD.
Findings
Matches center dependence and Casimir scaling of string tension
Predicts logarithmic broadening of the flux tube
Incorporates the Luscher term in the potential
Abstract
I describe how the gluon chain model of QCD string formation meets a number of criteria which are required of any theory of the confining force, including: the correct center dependence and (at large-N) Casimir scaling of the string tension, the logarithmic broadening of the QCD flux tube, and the existence of a Luscher term in the static quark potential.
