Popis: We calculate the centrality dependence for coherent photoproduction of very low-pTJ/ψ at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies within the impact parameter-dependent saturated color dipole model. By using the large equivalent photon fluxes, we present the differential cross-section of very low-pTJ/ψ produced by coherent photonuclear in peripheral heavy ion collisions. The numerical results demonstrate that our calculation agrees with J/ψ data in peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) energies.
