Electroweak Physics at the LHC

This talk summarises results on electroweak processes at the Large Hadron Collider by the ATLAS and CMS collaborations. It covers results from sqrt(s) = 7, 8 TeV data from LHC Run-1, and also results using sqrt(s) = 13 TeV data from the recent LHC Run-2. The status of cross section measurements of single and di-boson production, as well as rare electroweak processes such as vector boson scattering and tri- boson production are presented. Processes that can not be observed (yet) allow to set limits on the respective cross sections. All observations are compatible with Standard Model descriptions and allow to constrain new physics which would manifest through extra gauge couplings, or Standard Model gauge couplings deviating from their predicted value. Limits on such anomalous gauge couplings are derived.
