Description
The inclusive electron spectrum from B-meson decays is measured using a sample of 467 million BBbar pairs recorded with the BABAR detector. Contributions from CKM-favored and CKM-suppressed semileptonic B decays, from secondary decays of charm hadrons and from continuum e+e- -> qqbar annihilations are evaluated using a simultaneous fit to data collected at the Y(4S) resonance and at collision energies below the BBbar production threshold. The partial branching fraction BF(B -> Xu l nu, E_min*) is evaluated using four different models for the CKM-suppressed decays as a function of the minimum electron energy in the B rest frame, and corresponding values of |Vub| are determined.
