Theoretical Developments in Inclusive B Decays
arXiv:hep-ph/9904460
Abstract
Some recent theoretical work on inclusive B decays relevant for the model independent determination of |V_{ub}| and |V_{cb}| is summarized. The theoretical predictions and their reliability for several differential decay distributions in B -> X_{c,u}e nu and B -> X_s gamma are reviewed. These can be used to determine certain important HQET matrix elements. The upsilon expansion and ways of testing it are discussed.
