| 英文摘要 | The production of J/psi mesons in continuum e(+)e(-) annihilations has been studied with the BABAR detector at energies near the Y(4S) resonance. The mesons are distinguished from J/psi production in B decays through their center-of-mass momentum and energy. We measure the cross section e(+)e(-) --> J/psiX to be 2.52 +/- 0.21 +/- 0.21 pb. We set a 90% C.L. upper limit on the branching fraction for direct Y(4S) --> J/psiX decays at 4.7 x 10(-4). |
