dc.description.abstract | We report on a study of inclusive B − and ¯¯¯ B 0 meson decays to D 0 X , ¯¯¯ D 0 X , D + X , D − X , D + s X , D − s X , Λ + c X , ¯¯¯ Λ − c X , based on a sample of 231 × 10 6 B ¯¯¯ B events recorded with the BABAR detector at the Υ ( 4 S ) resonance. Events are selected by completely reconstructing one B and searching for a reconstructed charm particle in the rest of the event. From the measured branching fractions of these decays, we infer the number of charm and anticharm particles per ¯¯¯ B decay, separately for charged and neutral parents. We derive the total charm yield per B − decay, n − c = 1.208 ± 0.023 ± 0.040 + 0.035 − 0.029 , and per ¯¯¯ B 0 decay, n 0 c = 1.203 ± 0.030 ± 0.034 + 0.044 − 0.035 where the first uncertainty is statistical, the second is systematic, and the third reflects the charm branching-fraction uncertainties. We also present the charm momentum distributions measured in the ¯¯¯ B rest frame. | - |
