アブストラクト: Due to the discovery of renormalon cancellation, it
became possible to describe the nature of a heavy
quarkantiquark
system (such as bottomonium) based
on perturbative QCD, both qualitatively and
quantitatively. Accordingly, interpretaions of the heavy
quark mass and interquark force have been modified
considerably. I overview what has been understood and
some of theoretical progress since then. The UV part of
the interquark potential can be computed in perturbative
QCD. We show that a "Coulomb+linear" potential is
obtained as the prediction
