Abstract
Ultra-peripheral heavy ion collisions are a source of photons which collide with the other nucleus producting single vector meson or they can collide with each other producing a pair of particles. The contribution from fermionic boxes, resonance scattering, VDM-Regge model, two-gluon exchange and pionic background will be studied to two-photon production. Each of these processes dominates at different range of two-photon invariant masses. Our results for nuclear cross section are in good agreement with recently measured ATLAS and CMS data. Predictions including ALICE and LHCb semi(acceptance) for the next run at the LHC will be shown.
