Electromagnetic processes in ultra-peripheral Pb+Pb collisions with ATLAS

The large equivalent-photon fluxes accompanying Pb ion beams at the LHC initiate photon-photon interactions, which occur when the colliding nuclei have large impact parameter (ultra-peripheral collisions). The ATLAS collaboration has carried out a range of measurements related with two-photon interactions at high energies using recently recorded Pb+Pb collision data taken at sNN=5.02 TeV.
