Abstract

This paper describes new measurements from CLEO of the inclusive B-->D (s)(+)X branching fraction as well as the B+-->D-s()(+)(D) over bar(* )(0) and B-0-->D-s()D-+(*)(-) branching fractions. The inclusive bran ching fraction is B(B-->D(s)(+)X)=(12.11+/-0.39+/-0.88+/-1.38)% where the first error is statistical, the second is the systematic error, an d the third is the error due to the uncertainty in the D-s(+)-->phi pi (+) branching fraction. The branching fractions for the B-->D-s()(+)( D) over bar() modes are found to be between 0.9% and 2.4% and are sig nificantly more precise than previous measurements. The sum of the B-- >D-s()(+)(D) over bar(*) branching fractions is consistent with the r esults of fits to the inclusive D-s(+) momentum spectrum. Factorizatio n is used to arrive at a value for f(Ds), the D-s(+) decay constant.
