The Infrared Boundary of Perturbative QCD
arXiv:hep-ph/0109134
Abstract
Evidence is reviewed suggesting that QCD remains a perturbative theory with a (relatively) small coupling constant down to a distinct infrared boundary on perturbative physics, a boundary corresponding to the momentum scale associated with a beta-function pole.
