Diboson and Electroweak Physics at ATLAS

LHC data at centre-of-mass energies of 7 and 8 TeV are used to perform measurements of electroweak diboson and Zjj production with the ATLAS detector. These measurements comprise combinations of W, Z and isolated photons, and use leptonic as well as semi-leptonic decay channels. No significant deviations from the Standard Model have been observed and the measurements are used to place constraints on anomalous gauge boson couplings. In addition, the prospects for vector boson scattering and triboson production at the LHC at a center-of-mass energy of 14 TeV are discussed.
