The QCD static energy at NNNLL
arXiv:0906.1390 · doi:10.1103/PhysRevD.80.034016
Abstract
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.
