Abstract

The goal of the SIMBA collaboration is to provide a global fit to the available measurements of inclusive B?Xs? and B?Xul? decays. By performing a global fit one is able to simultaneously determine the relevant normalizations, i.e. the total B ? Xs? rate and the CKM-matrix element |Vub|, together with the required hadronic parameters, most importantly the b-quark mass and the b-quark distribution function in the B-meson, called the shape function. In this talk, the current status on the model-independent determination of the shape function and |C7inclVtbVts*|, which parametrizes the total B?Xs? rate, from a global fit to the available B?Xs? measurements from BABAR and Belle is presented. In particular, the theoretical uncertainties originating from variations of the different factorization scales are evaluated.
