摘要：

The production of J /psi mesons in p+p and p+Pb collisions is studied in the framework of color-glass condensate together with a simple color evaporation model. Considering the nuclear effects with the Glauber-Gribov approach, we calculate the cross section and the nuclear modification factor of forward J/psi production in p+Pb collisions at root s = 5.02 TeV. Then, the backward J/psi production in p+Pb collisions at root s = 8.16 TeV is also analyzed. In our calculation, the phenomenology KLR-AdS/CFT model and the rcBK approach, which are valid at a small x, are used to calculate the three-point function. It is shown that the theoretical results fit well with the experimental data from ALICE and LHCb.
