title = "Flavor-specific inclusive B decays to charm",

abstract = "We have measured the branching fractions for B → D{\textregistered}X, B → D{\textregistered}X, and B → D{\textregistered}Xℓ+v. From these results and some previously measured branching fractions, we obtain B(b → cc{\textregistered}s) = (21.9 ± 3.7)%, B(b → sg) < 6.8% at 90% C.L., and B(D0 → K− π+ = (3.69 ± 0.20)%. Implications for the “B semileptonic decay problem” (measured branching fraction being below theoretical expectations) are discussed. With the increase in the value of B(b → cc{\textregistered}s) due to B → DX, the discrepancy is no longer statistically compelling.",
