Abstract
We report on measurements of the inclusive production of J, psi' and c hi(c) mesons in hadronic Z decays, based on 3.2 million hadronic event s collected using the L3 detector at LEP. The J and psi' mesons are re constructed through their decays into lepton pairs, while the chi(c) m esons are reconstructed via the decay mode chi(c) --> J + gamma. The m easured branching fractions are: Br(Z --> J + X) = (3.40 +/- 0.23 (sta t.) +/- 0.27 (sys.)) x 10(-3), Br(Z --> psi' + X) = (1.6 +/- 0.5 (stat .) +/- 0.3 (sys.)) x 10(-3) Br(Z --> chi(cl) + X) = (2.7 +/- 0.6 (stat .) +/- 0.5 (sys.)) x 10(-3). In the absence of a clear chi(c2) signal, the upper limit at 90% C.L. is set: Br(Z --> chi(c2) + X) < 3.2 x 10( -3). (C) 1997 Elsevier Science B.V.
