The J/\\psi we compute here includes the direct J/\\psi from the partonic fusion processes and the J/\\psi coming from the radiative decays of \\chi_J's both in the color octet and singlet channel. The high p_T J/\\psi production cross section is computed within the PHENIX detector acceptance ranges: -0.35 < \\eta < 0.35 and 1.2 < \\|\\eta| < 2.4, the central electron and forward muon arms.
