Abstract
We derive the lepton spectrum in semileptonic beauty decays from a nonperturbative treatment of QCD; it is based on an expansion in with being the heavy flavour quark mass. The leading corrections arising on the level are completely expressed in terms of the difference in the mass of the heavy hadron and the quark. Nontrivial effects appear in terms affecting mainly the endpoint region; they are different for meson and baryon decays as well as for beauty and charm decays.
