Hadronic Spectrum in Inclusive Semileptonic B Decays

Abstract

We evaluate the inclusive semileptonic B decay spectrum as a function of the final-state hadrons energy to second order in the inverse quark mass expansion and tree level in ${\alpha }_s$. We argue that there is an energy interval below the $c$ production threshold that could be used to determine $V_{ub}$.
