Semileptonic B Meson Decays
We review some of the most important topics in the semileptonic decays of B mesons, with emphasis on recent results from CLEO and LEP. We discuss the current data samples, inclusive and exclusive semileptonic decay branching fractions, and form factor measurements in the context of HQET.
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 کاملSemileptonic B Decays
We report studies of semileptonic decays, B → X c ℓν, based on a sample of 88 million BB events recorded with the BABAR detector. We have measured four moments of the electron energy distribution and four moments of the hadronic mass distribution, each as a function of the minimum electron energy. From these moments we determine the inclusive branching fraction, the CKM matrix element |V cb |, ...
متن کاملSemileptonic B Decays in Babar
BABAR measurements involving semileptonic decays of B mesons are reviewed. Attention is focused on the extraction of |Vub | and |Vcb | elements of the Cabibbo-KobayashiMaskawa quark mixing matrix. Recent results of inclusive and exclusive approaches are presented. The study of semileptonic B decays provides observables for the extraction of |Vub| and |Vcb| elements of Cabibbo-Kobayashi-Maskawa ...
