Description

Abstract: Photon fusion is a rare and interesting process at proton and ion colliders, involving purely electroweak interactions and allowing precision tests of the gauge structure of the Standard Model. Experimentally it has a remarkably clean signature with little (if any) remnant activity from the interacting beam particles, although this signature is very difficult to identify in the harsh experimental conditions at the LHC. In this seminar, recent ATLAS photon fusion results are presented: the observation of photo-produced weak-boson pair-production, cross-section measurement of lepton pair production with proton tagging in the ATLAS Forward Proton Spectrometer, and studies of light-by-light scattering.
