DESCRIPTION:The Dalitz-plot analysis technique is used to study the interm
 ediate\nstructure of the decay Bs -> D0bar K- pi+.  The ability of this ap
 proach\nto distinguish the spin of intermediate resonances allows the prev
 iously\nobserved state DsJstar(2860) to be resolved into two contributions
 :\nDs1star(2860) and Ds3star(2860).  This is the first time that a spin-3 
 heavy\nflavour particle has been observed and the first observation of a B
  meson\ndecaying to a spin-3 particle.\nI will give an introduction to Ds 
 meson spectroscopy\, the physics of the\nfamily of B(s) -> Dhh decays and 
 the Dalitz-plot analysis technique\,\nbefore discussing in detail the rece
 nt results of the Bs -> D0bar K- pi+\nanalysis and their implications.
