Abstract

We report a measurement of the inclusive electron energy spectrum for semileptonic decays of B mesons in a data sample of 52 million γ(45)→BB̄ decays collected with the BABAR detector at the PEP-II asymmetric-energy B-meson factory at SLAC. We determine the branching fraction, first, second, and third moments of the spectrum for lower cutoffs on the electron energy between 0.6 and 1.5 GeV. We measure the partial branching fraction to be B(B→Xeν,E_e>0.6 GeV)= [10.36±0. 06(stat.)±0.23(sys.)]%.
