Abstract

We report new measurements of the differential and total branching ratios for inclusive [Formula presented] decay to [Formula presented], [Formula presented], and [Formula presented] and the first measurement of the same quantities for inclusive [Formula presented] decay to [Formula presented]. Here [Formula presented] is the mixture of [Formula presented] and [Formula presented] from [Formula presented] decay. Furthermore, since more than one charm particle (or antiparticle) of the same kind can be produced in [Formula presented] decay, here “inclusive [Formula presented] branching ratio” is used to mean the average number of charm particles and their antiparticles of a certain species produced in [Formula presented] decay. We obtain the following results (the first error is statistical, the second systematic of this analysis, the third propagated from other measurements): [Formula presented] [Formula presented] [Formula presented][Formula presented] [Formula presented] The following ratio of branching ratios is not affected by most of the systematic errors: [Formula presented][Formula presented] We also report the first measurement of the momentum-dependent [Formula presented] polarization and a new measurement of the [Formula presented] polarization in inclusive [Formula presented] decay. Using these measurements and other CLEO results and making some additional assumptions, we calculate the average number of [Formula presented] and [Formula presented] quarks produced in [Formula presented] decay to be [Formula presented]. © 1997 The American Physical Society.
