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 N4LO in αs. At the same order, this provides the logarithmic terms of the singlet static potential in pNRQCD and the logαs terms of the static energy.
