Abstract
The production of polarized \(J/\psi\) mesons at the NICA (Nuclotron based Ion Collider fAcility) energy of \(\sqrt{s}=27\) GeV is studied on the basis of the generalized parton model in the leading order of perturbative QCD. The hadronization of a \(c\bar{c}\) quark pair to a \(J/\psi\) meson is described within the model of nonrelativistic QCD. Nonperturbative model parameters are determined on the basis of a comparison with available experimental data on the production of prompt \(J/\psi\) mesons at the energies of \(\sqrt{s}=19.4\) GeV (NA3) and \(\sqrt{s}=200\) GeV (PHENIX).
Abstract The production of polarized \(J/\psi\) mesons at the NICA (Nuclotron based Ion Collider fAcility) energy of \(\sqrt{s}=27\) GeV is studied on the basis of the generalized parton model in the leading order of perturbative QCD.在非相对论QCD模型中描述了一个（c\bar{c}\）夸克对到一个（J/\psi\）介子的强子化。非微扰模型参数是在与能量为 \(\sqrt{s}=19.4\) GeV (NA3)和 \(\sqrt{s}=200\) GeV (PHENIX)时产生瞬时 \(J/\psi\) 介子的现有实验数据进行比较的基础上确定的。
