MEASUREMENT OF THE BRANCHING FRACTIONS FOR INCLUSIVE B{sup -} AND {bar B}{sup 0} DECAYS TO FLAVOR-TAGGED D, D{sub S} AND LAMBDA{sub C}
Abstract
The authors report on the inclusive branching fractions of B{sup -} and of {bar B}{sup 0} mesons decaying to D{sup 0}X, {bar D}{sup 0}X, D{sup +}X, D{sup -}X, D{sub s}{sup +}X, D{sub s}{sup -}X, {Lambda}{sub c}{sup +}X, {bar {Lambda}}{sub c}{sup -}X, based on a sample of 88.9 million B{bar B} events recorded with the BABAR detector at the {Upsilon}(4S) resonance. Events are selected by completely reconstructing one B and searching for a reconstructed charmed particle in the rest of the event. The authors measure the number of charmed and of anit-charmed particles per B decay and derive the total charm yield per B{sup -} decay, n{sub c}{sup -} = 1.313 {+-} 0.037 {+-} 0.037 {+-} 0.062{sub -0.043}{sup +0.063}, and per {bar B}{sup 0} decay, n{sub c}{sup 0} = 1.276 {+-} 0.062 {+-} 0.058{sub -0.046}{sup +0.066} where the first uncertainty is statistical, the second is systematic, and the third reflects the charm branching-fraction uncertainties.
