摘要：

Spectator model decay rates are predicted for inclusive semileptonic decays of the LAMBDA(b) baryon and the B meson, in the limit of a very heavy b quark, in lowest order Of perturbative QCD. For charmless final states the result is only achieved in a short distance limit, sharing similarities with the deep inelastic scattering situation, and allowing for a parton model interpretation. In all cases these results are expressed in terms of sum rules derived with the help of equal-time, local current algebra.
