Abstract
We have measured the branching fractions for B --> (D) over bar X, B --> DX, and B --> (D) over bar Xl(+)v. From these results and some previously measured branching fractions, we obtain B(b --> c (c) over bar s) = (21.9 +/- 3.7)%, B(b --> sg) < 6.8% at 90% C.L., and B(D-0 --> K- pi(+)) = (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 --> c (c) over bar s) due to B --> DX, the discrepancy is no longer statistically compelling. [S0031-9007(97)05231-9].
