Received 12 November 2006; published 8 June 2007
J/ψ production in p+p collisions at √s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over a rapidity range of -2.2<y<2.2 and a transverse momentum range of 0<pT<9 GeV/c. The size of the present data set allows a detailed measurement of both the pT and the rapidity distributions and is sufficient to constrain production models. The total cross section times the branching ratio is BllσppJ/ψ=178±3stat±53sys±18norm nb.
