چکیده
We report a measurement of the inclusive charmless semileptonic branching fraction of B mesons in a sample of 89 x 10(6) (-)BB events recorded with the BABAR detector at the Upsilon(4S) resonance. Events are selected by fully reconstructing the decay of one B meson and identifying a charged lepton from the decay of the other B meson. The number of signal events is extracted from the mass distribution of the hadronic system accompanying the lepton and is used to determine the ratio of branching fractions B((-)B-->X(u)lnu;)/B((-)B-->Xlnu;)=[2.06+/-0.25(stat)+/-0.23(syst)+/-0.36(theo)]x10(-2). Using the measured branching fraction for inclusive semileptonic B decays, we find B((-)B-->X(u)lnu;)=[2.24+/-0.27(stat)+/-0.26(syst)+/-0.39(theo)]x10(-3) and derive the Cabibbo-Kobayashi-Maskawa matrix element |V(ub)|=[4.62+/-0.28(stat)+/-0.27(syst)+/-0.48(theo)]x10(-3).

متن کاملcharmless semileptonic branching ratio of b hadrons
We calculate the inclusive charmless semileptonic decay width of the B meson using a QCD-based approach. This approach is able to account for both dynamic and kinematic effects of nonperturbative QCD. The charmless semileptonic decay width is found to be enhanced by long-distance strong interactions by +(7± 5)% with respect to the free quark decay width. Using the resulting theoretical value fo...
متن کاملSemileptonic 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...

PACS numbers: 13.20.He, 12.15.Hh, 12.40.Vv. 11.30.Hv The first measurement of an exclusive charmless semileptonic B decay has been reported recently by the CLEO Collaboration [1,4].

متن کاملUOM/NPh/HQP/00-3 UH-511-962-00 Inclusive charmless semileptonic decay of Λb and Br(b → Xulνl)
We study the inclusive charmless semileptonic decay of Λb, Λb → Xulνl, in the framework of heavy quark expansion and find that the rate is substantially enhanced by spectator effect. We obtain Br(b → Xulνl) to be 1.13× 10 −3 for |Vub| = 3.3× 10 . We discuss our result in light of the recent LEP measurements of the charmless semileptonic branching ratio where such enhancement was not taken into ...
متن کاملFurther remarks on the isospin breaking in charmless semileptonic B decays
We consider the isospin breaking corrections to charmless semileptonic decays of B mesons. Both, the recently measured branching ratios of exclusive decays by the CLEO Collaboration and the end-point region of the inclusive lepton spectrum in form factor models, can be affected by these corrections. Isospin corrections can affect the determination of |Vub| from exclusive semileptonic B decays a...
