Abstract
We have used the CLEO-II detector at the Cornell Electron Storage Ringe (CESR) to study the inclusive production of charmonium mesons in a sample of 2.15 million BB¯ events. We find inclusive branching fractions of (1.12±0.04±0.06)% for B→J/ψX, (0.34±0.04±0.03)% for B→ψ′X, and (0.40±0.06±0.04)% for B→X. We also find some evidence for the inclusive production of , and set an upper limit for the branching fraction of the inclusive decay B→X of 0.9% at 90% confidence level. Momentum spectra for inclusive J/ψ, ψ′, and production are presented. These measurements are compared to theoretical calculations.
