| 英文摘要 | We have measured the probability, (n) over bar(g --> c (c) over tilde), of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods have been applied to events with a three-jet topology. One method relies an tagging charmed hadrons by identifying a lepton in the lowest energy jet. The other method uses a neural network based on global event shape parameters. Combining both methods, we measure (n) over bar(g --> c (c) over bar) = [2.45 +/- 0.29 + 0.53]%.
