Descripción
We review weakly-bound heavy quarkonium systems using effective field theories
of QCD. We concentrate on potential Non-Relativistic QCD, which provides with a well founded connection between QCD and descriptions of the heavy quarkonium dynamics in terms of Schr\"odinger-like equations. This connection is obtained using standard quantum field theory techniques such as dimensional regularization. Renormalization group equations naturally follow. We also briefly review some applications, which include spectroscopy, radiative transitions, Non-Relativistic sum rules, inclusive decays, and electromagnetic threshold production.
