Measurement of the Ratio ${\cal B}\xspace(\B^+ \to X e ν)$ / ${\cal B}\xspace(\B^0 \to X e ν)

The BABAR Collaboration, B. Aubert

We report measurements of the inclusive electron momentum spectra in decays of charged and neutral B mesons, and of the ratio of semileptonic branching fractions ${\cal B}\xspace(\…
