Title: Measurement of inclusive production of charmonium states in B meson decays

Abstract

The authors reconstruct the charmonium mesons J/{psi}, {psi}(2S) and {chi}{sub c} using a sample of 8.46 x 10{sup 6} B{bar B} events collected by the BABAR detector operating at e{sup +}e{sup -} center of mass energies near the {Lambda}(4S) resonance. by measuring rates relative to the branching fraction of the J/{psi}, they obtain preliminary inclusive B branching fractions of (0.25 {+-} 0.02 {+-} 0.02)% to the {psi}(2S) and (0.39 {+-} 0.04 {+-} 0.04)% to the {chi}{sub c1}, and set a 90% confidence level limit of 0.24% on decays through the {chi}{sub c2}.
