Abstract

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured J/ψ production in proton-proton collisions at \(\sqrt{s}\) = 200 GeV using data from the 2001–2002 collider run. Distributions of rapidity and transverse momentum are presented and compared with theoretical predictions. The total cross section and mean p T are calculated and compared to fixed-target results. The total J/ψ cross section is 4.0 ± 0.6(stat) ± 0.6(sys) ± 0.4(abs) μb. The mean p T is 1.80 ± 0.23(stat) ± 0.16(sys) GeV/c.
