The static potential in QCD - a full Two-Loop Calculation

A full analytic calculation of the two-loop diagrams contributing to the static potential in QCD is presented in detail. Using a renormalization group improvement, the ``three-loop'' potential in momentum space is thus derived and the third coefficient of the $β$-function for the V-scheme is given. The Fourier transformation to position space is then performed, and the result is briefly discussed.

The static quark-antiquark potential in QCD to three loops

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.
