One-Particle Inclusive B sub s -> D bar sub s X Decays
  We discuss one-particle inclusive B sub s -> D bar sub s X decays using a QCD based method already applied to B -> D bar X. A link between the right charm non-perturbative form factors of the semi-leptonic decays and those of the non-leptonic decays is established. Our results are compatible with current experimental knowledge.
