Abstract

The rate of gluon splitting into cc pairs in hadronic Z decays is measured using the data sample collected by ALEPH from 1991 to 1995. The selection is based on the identification of leptons (electrons and muons) originating from semileptonic charm decays, and on the topological properties of signal events. The result derived from the selected sample is g(cc) = (3.26 +/- 0.23(stat) +/- 0.42(syst))%. (C) 2003 Published by Elsevier Science B.V.
