"Coulomb+linear" form of the static QCD potential in operator-product-expansion

Abstract

The static QCD potential is analyzed in operator-product-expansion within potential-NRQCD framework when r << 1/Lambda_{QCD}. We show that the leading short-distance contribution to the potential, defined as a perturbatively computable Wilson coefficient, can be expressed, up to O(r^2), as a ``Coulomb+linear'' potential. It coincides with the ``Coulomb+linear'' potential obtained previously from the renormalon-dominance hypothesis. Non-perturbative contributions are of order r^2 and subleading.
