J/psi production in p+p collisions at square root 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 Bll sigma pp J/psi=178+/-3stat+/-53sys+/-18norm nb.
在布鲁克海文国家实验室相对论重离子对撞机上，PHENIX实验测量了质心能量平方根(\sqrt{s}=200)GeV的(p + p)碰撞中(J/\psi)粒子的产生，其快度范围为(-2.2 < y < 2.2)，横向动量范围为(0 < p_T < 9)GeV/c。当前数据集的规模使得对(p_T)和快度分布进行详细测量成为可能，并且足以约束产生模型。总截面乘以分支比为(B_{ll}\sigma_{pp}J/\psi = 178 \pm 3_{stat} \pm 53_{sys} \pm 18_{norm})nb。
