An Inclusive Look at Charmless Inclusive B Decays

Over the last two years there has been a considerable theoretical research effort that would lead to a high precision measurement of the CKM matrix element |Vub| from inclusive charmless B decays. Accurate determination of |Vub| would allow us to test the Standard Model and search for possible deviations from its predictions. In a series of papers, written in collaboration with Stefan Bosch, Bjorn Lange and Matthias Neubert, we have explored both the perturbative and non perturbative aspects of the problem. This effort has culminated in our latest "state-of-art" work on the extraction of |Vub|, which the BaBar and Belle experiments have already started to implement. -
