QCD static energy at next-to-next-to-next-to leading-logarithmic accuracy

QCD static energy at next-to-next-to-next-to leading-logarithmic accuracy

We compute the static energy of QCD at short distances at next-to-next-to-next-to-leading logarithmic accuracy in terms of the three-loop singlet potential. By comparing our results with lattice data we extract the value of the unknown piece of the three-loop singlet potential.
