英文摘要We report on a study of inclusive B- and (B) over bar (0) meson decays to (DX)-X-0, (D) over bar X-0, D+X, D-X, Ds+X, Ds-X, Lambda X-+(c), (Lambda) over bar X--(c), based on a sample of 231x10(6) (B) over bar events recorded with the BABAR detector at the Y(4S) 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) over bar decay, separately for charged and neutral parents. We derive the total charm yield per B- decay, n(c)(-)=1.208 +/- 0.023 +/- 0.040(-0.029)(+0.035), and per (B) over bar (0) decay, n(c)(0)=1.203 +/- 0.030 +/- 0.034(-0.035)(+0.044) 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) over bar rest frame.
