The inclusive production of charmonium mesons in B meson decay has been studied in a 20.3 fb-1 data set collected by the BABAR experiment operating at the Y(4S) resonance. Branching fractions have been measured for the inclusive production of the charmonium mesons J/ψ, ψ(2S), χc1, and χc2. The branching fractions are also presented as a function of the center-of-mass momentum of the mesons and of the helicity of the J/ψ. © 2003 The American Physical Society.
