## Abstract

The total energy of a static quark-antiquark pair E_{tot}(r)=2m_{pole}+V_{QCD}(r) is known to include O(Λ_{QCD} ^{3}r^{2}) and O(Λ_{QCD} ^{3}/m‾^{2}) renormalon uncertainties in the large-β_{0} approximation, after canceling O(Λ_{QCD}) renormalons. We compute the (renormalon-free) genuine UV part in terms of the MS‾ mass m‾, extending a recently-proposed method which conforms with OPE. In particular the r-independent part is determined. The result would help understanding the nature of E_{tot}(r) in the context of OPE with renormalon subtraction.
