Semileptonic Decays of D and B Mesons, Part Ii Iv. B-meson Semileptonic Decays the Inclusive Semileptonic Branching Fraction
In the following sections, we discuss some of the key questions related to semileptonic decays of B mesons: the inclusive semileptonic branching fraction, the determination of jV cb j and jV ub j from inclusive and exclusive measurements, recent progress in exclusive semileptonic decays, and form factor measurements and tests of heavy-quark eeective theory. We emphasize the uncertainties that a...
متن کاملInclusive semileptonic B decays
In the framework of the Standard Model, the quark sector is characterised by a rich pattern of flavourchanging transitions, described by the CabibboKobayashi-Maskawa (CKM) matrix. The quark transitions B → Xclν and B → Xulν provide a way for determining these CKM matrix elements. This report reviews the experimental measurements used to extract the quark mixing parameters |Vcb| and |Vub| from t...

متن کاملRadiative Corrections to Nonleptonic Inclusive B Decays and the Semileptonic Branching Ratio of B Mesons
We calculate the radiative corrections to the nonleptonic inclusive B decay mode b → cud taking into account the charm quark mass. The corrections increase the decay rate by (4–8)%, depending on the renormalization point. Using these results, we obtain an improved theoretical prediction for the semileptonic branching ratio of B mesons. This talk relies on work done in collaboration with E. Baga...
