B meson semileptonic decays play a key role in testing the Standard Model: they provide the determination of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements, and serve as interesting probe of new physics. However, the long-standing tension in the CKM matrix elements, |V_ub| and |V_cb|, between the exclusive and inclusive decays suggests that theoretical and\/or experimental uncertainties have not been fully understood.
