The static quark-antiquark potential in QCD to three loops

arXiv:hep-ph/9610209 · doi:10.1103/PhysRevLett.78.602

Abstract

The static potential between an infinitely heavy quark and antiquark is derived in the framework of perturbative QCD to three loops by performing a full calculation of the two-loop diagrams and using the renormalization group. The contribution of massless fermions is included.
