The inclusive cross section for J/ψ production times the branching ratio B(J/ψ→μ + μ -) has been measured in the forward pseudorapidity region: B×dσ[p̄+p→J/ψ(p r>10 GeV/c,2.1<|η|<2.6)+X]/dη = 192±9(stat) ±29(syst) pb. The results are based on 74.1±5.2 pb -1 of data collected by the CDF Collaboration at the Fermilab Tevatron Collider. The measurements extend earlier measurements of the D0 Collaboration to higher p T J/ψ. In the kinematic range where the experiments partially overlap, these data are in good agreement with previous measurements.
