Theoretical Developments in Inclusive B Decays
Abstract
Some recent theoretical work on inclusive B decays relevant for the model independent determination of |Vub| and |Vcb| is summarized. The theoretical predictions and their reliability for several differential decay distributions in B -> Xc,ue nu and B -> Xs gamma are reviewed. These can be used to determine certain important HQET matrix elements. The upsilon expansion and ways of testing it are discussed.
