Abstract

Evidence is presented for the production of prompt J/ψ mesons (not originating in b-hadron decays) in hadronic Z⁰ decays. Using a sample of 3.6 million hadronic events, 24 prompt J/ψ candidates are identified from their decays into e⁺e^- and μ⁺μ^- pairs. The background is estimated to be 10.2±2.0 events. The following branching ratio for prompt J/ψ production is obtained: Br(Z⁰ → prompt J/ψ + X) = (1.9 ± 0.7 ± 0.5 ± 0.5) · 10^-4, where the first error is statistical, the second systematic and the third error accounts for uncertainties in the prompt J/ψ production mechanism.

N2 - Evidence is presented for the production of prompt J/ψ mesons (not originating in b-hadron decays) in hadronic Z0 decays. Using a sample of 3.6 million hadronic events, 24 prompt J/ψ candidates are identified from their decays into e+e- and μ+μ- pairs. The background is estimated to be 10.2±2.0 events. The following branching ratio for prompt J/ψ production is obtained: Br(Z0 → prompt J/ψ + X) = (1.9 ± 0.7 ± 0.5 ± 0.5) · 10-4, where the first error is statistical, the second systematic and the third error accounts for uncertainties in the prompt J/ψ production mechanism.
