摘要：

For more than a decade, measurements of the semileptonic branching ratio of hadrons containing a b quark disagreed with the Standard Model predictions. Very recently, a class of strong-interaction effects was found to significantly increase the non-leptonic b decay rate and thus bring the Standard Model prediction into agreement with the experiment. Final state charm quark mass effects should be determined to refine the theoretical description of b decays. Prospects for such improvement are discussed in this talk.
