Light and heavy multiquark spectroscopy
  The dynamics of multiquark binding is revisited in the light of the recent experimental results. It is emphasized that some configurations mixing light and heavy flavours are among the most favourable for stable or metastable multiquarks. The nuclear-physics type of approach predicting the so-called hadron-hadron molecules is compared to direct studies in terms of quark interaction.
