Probing a D6 + D0 state with D6-branes: SYM - Supergravity   correspondence at subleading level
  We probe a non-supersymmetric D6 + D0 state with D6-branes and find agreement at subleading order between the supergravity and super Yang-Mills description of the long-distance, low-velocity interaction.
