Photon--Photon Scattering at the LHC in Collisions of Nuclei

This paper is focused on an analysis of the light-by-light scattering in ultraperipheral heavy-ion collisions at the energy available at the CERN Large Hadron Collider. Here, contribution from fermionic boxes, resonance scattering, VDM-Regge model, two-gluon exchange as well as pionic background will be compared. Each of these processes dominates at different ranges of two-photon invariant masses. The usage of the equivalent photon approximation in the impact parameter space gives results that are in good agreement with recently measured ATLAS and CMS data. Predictions including ALICE and LHCb experimental cuts for the next run at the LHC are shown.
