Abstract
We report new measurements of the differential and total branching ratios for inclusive B decay to D-0, D+, and D*+ and the first measurement of the same quantities for inclusive B decay to D-*0. Here B is the mixture of B-d and B-u from Y(4S) decay. Furthermore, since more than one charm particle (or antiparticle) of the same kind can be produced in B decay, here ''inclusive B branching ratio'' is used to mean the average number of charm particles and their antiparticles of a certain species: produced in B decay. We obtain the following results (the first error is statistical, the second systematic of this analysis, the third propagated from other measurements): B(B --> (DX)-X-0) = (0.636 +/- 0.014 +/- 0.019 +/- 0.018), B(B --> D+X) = (0.0235 +/- 0.009 +/- 0.009 +/- 0.024), B(B --> (DX)-X-*0) = (0.247 +/- 0.012 +/- 0.018 +/- 0.018). B(B --> D*+X)= (0.239 +/- 0.011 +/- 0.014 +/- 0.009). The following ratio of branching ratios is not affected by most of:the systematic B(B --> (DX)-X-*0)/B(B --> D*+X) = (1.03 +/- 0.07 +/- 0.09 +/- 0.08). We also report the first measurement momentum-dependent D-*0 polarization and a new measurement of the D*+ polarization in inclusive B decay. Using these measurements and other CLEO results and making some additional assumptions, we calculate the average number of c and (c) over bar quarks produced in B decay to be [n(c)] = 1.10 +/- 0.05.
