Description
The measurement of the exclusive gamma+gamma -> ll production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV has been carried out by the ATLAS experiment at the LHC, based on an integrated luminosity of 4.6 fb-1. The ratios to the pure QED cross-section predictions are measured in the electron and muon channels and are found to be consistent
with the previous measurements at the LHC. When proton absorptive
effects due to finite proton size are taken into account in the theory calculation
the measured cross-sections are found to be consistent with
the prediction.
