Description
The most precise determinations of Vub and Vcb come from semileptonic B decays. The results of the B factories, analysed in the light of the most recent theoretical calculations, are puzzling. For both Vcb and Vub the
determination based on exclusive channels is about 3σ below the one based on inclusive decays.
This discrepancy has survived several checks and may be an indication of new physics. I will review
recent developments and future prospects of the Vxb determinations and briefly discuss new physics interpretations.
