Study of inclusive production of charmonium mesons in<i>B</i>decays

Abstract

The inclusive production of charmonium mesons in B meson decay has been studied in a 20.3 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ data set collected by the BABAR experiment operating at the $\ensuremath{\Upsilon}(4S)$ resonance. Branching fractions have been measured for the inclusive production of the charmonium mesons $J/\ensuremath{\psi},$ $\ensuremath{\psi}(2S),$ ${\ensuremath{\chi}}_{c1},$ and ${\ensuremath{\chi}}_{c2}.$ The branching fractions are also presented as a function of the center-of-mass momentum of the mesons and of the helicity of the $J/\ensuremath{\psi}.$
