INCLUSIVE J-PRODUCTION IN Z(0) DECAYS

Inclusive J production in Z0 decays is observed via the leptonic decay mode J → ℓ+ℓ- (ℓ = e,μ). We measure the branching ratio Br(Z0 → J + X) = (4.1 ± 0.7 (stat.) ± 0.3 (sys.)) × 10-3. We have calculated the fraction of the J mesons from b-hadron decay and find a branching ratio of Br(b → J + X)= (1...
