Abstract
We study J/ψproduction in pp collisions at RHIC within the PHENIX detector acceptance range using the color singlet and color octet mechanism which are based on pQCD and NRQCD. Here we show that the color octet mechanism reproduces the RHIC data for J/ψproduction in pp collisions with respect to the p_T distribution, the rapidity distribution and the total cross section at \sqrt s = 200 GeV. The color singlet mechanism leads to a relatively small contribution to the total cross section when compared to the octet contribution.
