The MIT Libraries is completing a major upgrade to DSpace@MIT.
Starting May 5 2026, DSpace will remain functional, viewable, searchable, and downloadable, however, you will not be able to edit existing collections or add new material.
We are aiming to have full functionality restored by May 18, 2026, but intermittent service interruptions may occur.
Please email dspace-lib@mit.edu with any questions.
Thank you for your patience as we implement this important upgrade.

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. | en_US |
