A model-independent determination of |Vub| can be obtained exploiting the sum rule for inclusive charmless semileptonic B-meson decays. The sum rule is derived on the basis of light-cone expansion and beauty quantum number conservation. The sum rule does not receive any perturbative QCD correction. In this determination of |Vub|, there is no perturbative QCD uncertainty, while the dominant hadronic uncertainty is avoided. Moreover, this method is not only theoretically quite clean, but… CONTINUE READING
