- Descripción
- A measurement of the inclusive charmless semileptonic branching fraction of beauty hadrons, b→Xuℓν, has been performed using almost two million hadronic Z decays collected by the L3 experiment at LEP, yielding the result: Br(b→Xuℓν)=(3.3±1.0±1.7)×10−3. The first uncertainty is statistical and the second is systematic. The modulus of the Cabibbo-Kobayashi-Maskawa matrix element Vub extracted from this measurement is: where the uncertainties are statistical, systematic and theoretical, respectively.
