Insight on confinement from the QCD effective charge

A. Deur

Like the Gell-Mann--Low coupling $I^\pm$ of QED, the effective charge $I^\pm_{g_{1}}$ is a physical, observable-defined running coupling that can serve as the QCD coupling $I^\pm_{s}$ . It can b…

The QCD Running Coupling

A. Deur

We describe the coupling of the strong force. Denoted as $I^\pm_{s}$ , it sets the strength of that force, just as $G$ or $I^\pm$ specify the strength of the gravity and electromagnetism. I…
