Equivalent photon approximation is used to calculate fiducial cross sections for dimuon production in ultraperipheral proton—proton and lead—lead collisions. Analytical formulae taking into account experimental cuts are derived. The results are compared with the measurements reported by the ATLAS collaboration.
