When the cancellation of the leading renormalon contributions is incorporated, the total energy of a bb̄ system Etot,bb̄(r)≡2mpole,b+VQCD(r) agrees well with the potentials used in phenomenological models for heavy quarkonia in the range 0.5 GeV-1≲r≲3 GeV-1. We provide a connection between the conventional potential-model approaches to the quarkonium spectroscopy and the recent computation based on perturbative QCD.
