Description
We derive the lepton spectrum in semileptonic b decays from a nonperturbative treatment of QCD; it is based on an expansion in 1/mQ with mQ being the heavy flavor quark mass. The leading corrections arising on the 1/mQ level are completely expressed in terms of the difference in the mass of the heavy hadron and the quark. Nontrivial effects appear in 1/mQ2 terms affecting mainly the end-point region; they are different for meson and baryon decays as well as for bottom and charm decays
