The logarithmic contribution to the QCD static energy at NNNNLO
Abstract
Using pNRQCD and known results for the field strength correlator, we calculate the ultrasoft contribution to the QCD static energy of a quark-antiquark pair at short distances at NNNNLO in alphas. At the same order, this provides the logarithmic terms of the singlet static potential in pNRQCD and the log alphas terms of the static energy.
