SUMMARY:From the deuteron to the beauteron - Tim Burns (Swansea)

DESCRIPTION:The potential between heavy hadrons due to pion-exchange can b
 e obtained in the quark model (as a straightforward generalisation of the 
 NN potential)\, or from heavy quark and chiral symmetries. The two approac
 hes are shown to be fundamentally equivalent\, and general results applica
 ble to both are discussed. Although the existence or otherwise of molecula
 r bound states depends on a poorly-constrained parameter\, the pattern of 
 which channels are most susceptible to binding is robust and generic\, and
  can be readily understood in terms of the strength and sign of the long-r
 ange potential. In this sense the predictions of  the molecular model are 
 more tightly constrained by experimental data than the compact multiquark 
 model\, which generally predicts a large number of states in all possible 
 spin and flavour channels. The predictions of the model are compared to so
 me recent puzzling experimental discoveries.\n\nThe slides of the presenta
