The LHC proton and lead high energy beams are source of intense light. The machine effectively serves as a photon-photon collider

producing interesting events with very little activity from the interacting beam particles which can be used to test the electroweak sector of the Standard Model. In the seminar, techniques to select these events will be discussed and new ATLAS results involving photon-photon fusion will be presented: the observation of the photon-induced production of the pair of electroweak bosons, the measurement of the dilepton pair produced in association to the proton detected in the forward proton spectrometer, and the light-by-light measurement in ulter-peripheral lead-lead collisions.
