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 ×𝑑⁢𝜎⁡[¯𝑝 +→𝑝⁢𝐽/𝜓⁢(𝑝𝑇 >10⁢GeV/𝑐,2.1 <|𝜂| <2.6) +𝑋]/d⁢𝜂 =192 ±9⁢(stat) ±2⁢9⁢(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 𝑝𝐽/𝜓𝑇. In the kinematic range where the experiments partially overlap, these data are in good agreement with previous measurements.
