On the quest for a holographic interpretation of the black hole   evaporation process
  This paper has been withdrawn by the authors because the Hawking radiation outside the core was just obtained for a specific (and somewhat unphysical) model of the tail. Interested readers should instead look at the more recent hep-th/0407191 where more general results are given for the formation and evolution of black-holes on the brane.
