Summary:A bstract The double longitudinal-spin asymmetry, A LL , of the J/ψ production in polarized proton-proton collisions is presented in this paper at QCD next-to-leading order. It is found that the obtained values of A LL are in general consistent with the PHENIX measurements. Various sets of the long-distance matrix elements (LDMEs) are employed in our calculation to study the possible theoretical uncertainties. It is found that, for p t < 5 GeV, all these LDMEs lead to almost the same results, which are within the tolerance of the experimental data uncertainties.
