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/psi, psi(2S), chi(c1), and chi(c2). 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/psi.

Abstract
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/psi, psi(2S), chi(c1), and chi(c2). 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/psi.File in questo prodotto:
