Abstract
This paper describes new measurements from CLEO of the inclusive B→X branching fraction as well as the →D and → branching fractions. The inclusive branching fraction is B(B→X)=(12.11±0.39±0.88±1.38)% where the first error is statistical, the second is the systematic error, and the third is the error due to the uncertainty in the →φ branching fraction. The branching fractions for the B→D modes are found to be between 0.9% and 2.4% and are significantly more precise than previous measurements. The sum of the B→D branching fractions is consistent with the results of fits to the inclusive momentum spectrum. Factorization is used to arrive at a value for , the decay constant. © 1996 The American Physical Society.
