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 RID A-8798-2012 RID C-5223-2009 RID C-5719-2008 RID D-1055-2009 RID A-2675-2009

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.

The inclusive B→Xcℓν branching fraction, B cℓν, the Cabibo-Kobayashi-Maskawa matrix element, and other heavy quark parameters were determined from a simultaneous fit moments of the hadronic mass and lepton-energy distributions in semileptonic B-meson decays. Using data recorded with BABAR detector, the values were mesured as function of the lower limit on the lepton energy. The vaues for Bceν were extracted using heavy quark expansions (HQE) to the order of 1÷m b3. The stated errors were referred to the experimental, HQE and additional theoretical uncertainties.
