Study of prompt $J/\psi$ production in hadronic Z decays
A measurement of prompt J/psi production with low model dependence is performed on 3.9 million hadronic Z decays collected by the ALEPH detector. The sample of J/psi at short decay-length shows an excess 46+/-12 prompt J/psi on a background of 57 B decay and 18 combinatorial events, yielding the bra...
