PROSPECTS FOR PHOTON-PHOTON MEASUREMENTS WITH TAGGED PROTONS IN ATLAS

In 2017, ATLAS has been equipped with a new, dedicated detector system allowing measurements of forward protons scattered at small angles in diffractive and electromagnetic processes. These ATLAS Forward Proton detectors (AFP) can operate during the standard high-luminosity LHC runs and collect large amounts of integrated luminosity. This gives a possibility to study rare interactions, in particular, the two-photon processes. The physics programme includes measurements of photon-photon interactions present in the Standard Model, as well as using searches for new physics. In this paper, the AFP detectors and physics goals are briefly presented.
