UV contributions to energy of a static quark-antiquark pair in large-β0 approximation
The total energy of a static quark-antiquark pair Etot(r)=2mpole+VQCD(r) is known to include O(ΛQCD3r2) and O(ΛQCD3/m‾2) renormalon uncertainties in the large-β0 approximation, after canceling O(ΛQCD) renormalons. We compute the (renormalon-free) genuine UV part in terms of the MS‾ mass m‾, extendin...
