Overview of constraints on new physics in rare B decays
  Recent improved measurements of B decays probing the b->s flavour-changing neutral current have put strong constraints on flavour violation beyond the Standard Model. This talk reviews a model-independent analysis of these decays, which allows to put constraints on dimension-six Delta(F)=1 effective operators. These constraints can be used in turn to test the flavour structure of any theory beyond the SM.
