The infrared behaviour of the static potential in perturbative QCD
arXiv:hep-ph/9903355 · doi:10.1103/PhysRevD.60.091502
Abstract
The definition of the quark-antiquark static potential is given within an effective field theory framework. The leading infrared divergences of the static singlet potential in perturbation theory are explicitly calculated.
