Determination of the branching fraction for B -> X(c)l nu decays and of vertical bar V-cb vertical bar from hadronic-mass and lepton-energy moments

X(c)lnu branching fraction, B-clnu, the Cabibbo-Kobayashi-Maskawa matrix element \V-cb\, and other heavy-quark parameters from a simultaneous fit to moments of the hadronic-mass and lepton-energy distributions in semileptonic B-meson decays, measured as a function of the lower limit on the lepton energy, using data recorded with the BABAR detector. Using heavy-quark expansions (HQEs) to order 1/m(b)(3), we extract B-cenu=(10.61+/-0.16(exp)+/-0.06(HQE))% and \V-cb\=(41.4+/-0.4(exp)+/-0.4(HQE)+/-0.6(th))x10(-3). The stated errors refer to the experimental, HQE, and additional theoretical uncertainties. -->

Popis: We determine the inclusive B-->X(c)lnu branching fraction, B-clnu, the Cabibbo-Kobayashi-Maskawa matrix element \V-cb\, and other heavy-quark parameters from a simultaneous fit to moments of the hadronic-mass and lepton-energy distributions in semileptonic B-meson decays, measured as a function of the lower limit on the lepton energy, using data recorded with the BABAR detector. Using heavy-quark expansions (HQEs) to order 1/m(b)(3), we extract B-cenu=(10.61+/-0.16(exp)+/-0.06(HQE))% and \V-cb\=(41.4+/-0.4(exp)+/-0.4(HQE)+/-0.6(th))x10(-3). The stated errors refer to the experimental, HQE, and additional theoretical uncertainties.
