Abstract

Recently, Neubert has suggested that a certain class of nonperturbative 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 corrections on Neubert's proposal. A connection between the end point of the electron spectrum in semileptonic B decay and the photon spectrum in b\ensuremath→s\ensuremathγ is outlined.
