Semileptonic B Decays Recent Results from Lep and Comparison with Υ(4s) Data
نویسنده
چکیده
Recent analyses of the LEP and Υ(4S) data have better outlined the picture of semileptonic B decays. Results on inclusive and exclusive decay branching fractions and on the extraction of the |V ub | and |V cb | elements of the CKM mixing matrix are discussed, together with some of the still open questions and the sources of model systematics.

Study of spectral moments in semileptonic decays of the b hadron with the DELPHI detector at LEP. The measurement of the moments of hadronic mass spectrum and of lepton energy spectrum based on a sample of semileptonic decays of the b hadron selected from Z 0 → b ¯ b events recorded with the Delphi detector at LEP, are presented. These results are interpreted in terms of constraints on the quar...

We review recent experimental results from CLEO and LEP experiments on hadronic decays of hadrons containing b quarks 1. We discuss charm counting and the semileptonic branching fraction in B decays and the color suppressed amplitude in B decay. 1 Charm counting and the semileptonic branching fraction A complete picture of inclusive B decay is beginning to emerge from recent measurements by CLE...
متن کاملRecent Results from LEP and Comparisons with Υ(4S) Experiments
Semileptonic (s.l.) B decays represent a favorable laboratory to study the dynamics of heavy quark decays, to determine the size of the |Vub| and |Vcb| CKM mixing matrix elements, crucial in the unitarity triangle test of the Standard Model, and to acquire informations on the structure of the B meson itself. The Aleph, Delphi, L3 and Opal experiments have analyzed together about 1.5 M s.l. B de...

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...
