title = "Measurement of the probability of gluon splitting into charmed quarks in hadronic Z decays",

abstract = "We have measured the probability, {\=n}(g→c{\=c}), 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 on 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}(g→c{\=c}) = [2.45 ± 0.29 ± 0.53]%.",
