Abstract

With the ARGUS detector at the e⁺e^- storage ring DORIS II, we have determined decay fraction and electron momentum spectrum of the inclusive decay mode B → eνX. Usinng lepton tags from the second B meson. in 209 000 γ(4S) → BB decays, we could determine the spectrum for all electron momenta p_e > 0.6 GeV/_c. Including the small extrapolation to p_e > 0, we find the model-independent decay fraction B(B → eνX) = (9.6 ± 0.5 ± 0.4)%. Adding D meson tags, our result is (9.7 ± 0.5 ± 0.4)%.
