  • Published 2002


The determination of |Vub| from inclusive semileptonic B decays is limited by uncertainties in modeling the decay distributions in b → u`ν transitions. The largest uncertainties arise from the limited knowledge of the appropriate b quark mass and Fermi momentum to use in the parameterization of the shape function. This paper presents a new method in which… (More)
