Coherent Photoproduction of Low-p[sub.T] Charmonium in Peripheral Heavy Ion Collisions within the Color Dipole Model

We calculate the centrality dependence for coherent photoproduction of very low-p[sub.T]J/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-p[sub.T]J/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.
