We calculate the centrality dependence for coherent photoproduction of very low-pTpT J/ψJ/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-pTpT J/ψJ/ψ produced by coherent photonuclear in peripheral heavy-ion collisions. The numerical results demonstrate that our calculation are agree with J/ψJ/ψ data in peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) energies.
