B-Meson Semileptonic Decays at BaBar
No full textWe report on the measurements of B-meson semileptonic decays at BABAR. The studies include precision measurement of |V{sub cb}| by a combined HQE fit to hadronic mass and electron energy spectral moments in inclusive B {yields} X{sub c}{ell}{nu} decays, measurements of |V{sub cb}| in inclusive and exclusive B {yields} X{sub u}{ell}{nu} decays, and measurements of B {yields} ({pi},{rho}){ell}{nu} decay rates
Measurement of the CKM matrix element |V(ub)| with B ---> rho e nu decays
No full textWe present a measurement of the branching fraction for the rare decays B-->rhoenu and extract a value for the magnitude of V-ub, one of the smallest elements of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix. The results are given for five different calculations of form factors used to parametrize the hadronic current in semileptonic decays. Using a sample of 55x10(6) B (B) over bar meson pairs recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring, we obtain B(B-0-->rho(-)e(+)nu)=(3.29+/-0.42+/-0.47+/-0.55)x10(-4) and \V-ub\=(3.64+/-0.22+/-0.25(-0.56)(+0.39))x10(-3), where the uncertainties are statistical, systematic, and theoretical, respectively
Extraction of |V ub | with Reduced Dependence on Shape Functions
No full textUsing BABAR measurements of the inclusive electron spectrum in B → Xueν decays and the inclusive photon spectrum in B → Xsγ decays, we extract the magnitude of the CKM matrix element V ub . The extraction is based on theoretical calculations designed to reduce the theoretical uncertainties by exploiting the assumption that the leading shape functions are the same for all b → q transitions (q is a light quark). The results agree well with the previous analysis, have indeed smaller theoretical errors, but are presently limited by the knowledge of the photon spectrum and the experimental errors on the lepton spectrum

Measurement of the B+ -> omega l(+) v and B+ -> eta l(+) v branching fractions
No full textWe present a study of the charmless semileptonic B-meson decays B+ -> omega l(+) v and B+ -> eta l(+) v. The analysis is based on 3.83 x 10(8) B (B) over bar B pairs recorded at the Gamma(4S) resonance with the BABAR detector. The omega mesons are reconstructed in the channel omega -> pi(+)pi(-)pi(0) and the eta mesons in the channels eta -> pi(+)pi(-)pi(0) and eta -> gamma gamma. We measure the branching fractions B(B+ -> omega l(+) v) = (1.14 +/- 0.16(stat) +/- 0.08(syst)) x 10(-4) and B(B+ -> eta l(+) v) = (0.31 +/- 0.06(stat) +/- 0.08(syst)) x 10(-4)
