                                    Resum

 Non-relativistic bound states have at least three well separated dynamical
   scales: the mass of the particles that form the bound state (hard), the
 typical relative momentun in the bound state (soft) and the typical binding
  energy (ultrasoft). This allows to introduce two effective field theories
  after sequentially integrating out first the hard scale and next the soft
scale. I will discuss how these effective field theories are obtained in the
case of QCD and QED, and how they allow to organise bound state calculations
                          in a very efficient way.
