QCD CORRECTIONS AND THE END-POINT OF THE LEPTON SPECTRUM IN SEMILEPTONIC B-DECAYS

Recently, Neubert has suggested that a certain class of nonperturbativ e corrections dominates the shape of the electron spectrum in the end point region of semileptonic B decay. Perturbative QCD corrections are important in the end point region. We study the effects of these corr ections on Neubert's proposal. A connection between the end point of t he electron spectrum in semileptonic B decay and the photon spectrum i n b --> sgamma is outlined.
