> 
> ABSTRACT:
> 
> J/Psi production in p+p collisions at \sqrt{s} = 200 GeV has been measured
> in the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) over
> a rapidity range of -2.2 < y < 2.2 and a transverse momentum range of 0 < pT
> < 9 GeV/c. The statistics available allow a detailed measurement
> of both the pT and rapidity distributions and are sufficient to constrain
> production models. The
> total cross section times branching ratio determined for J/Psi production is
> B_{ll} \sigma_{pp}^{J/Psi} = 178 +/- 3(stat) +/- 53(syst) +/- 18(norm) nb.
