Findings

Measurements of diboson production cross sections

Constraints on triple gauge couplings

Evidence for quartic gauge couplings

Abstract

These proceedings present measurements from ATLAS and CMS using proton-proton collisions with center-of-mass energies of 7 TeV and 8 TeV at the Large Hadron Collider that are sensitive to interactions between electroweak gauge bosons. Included analyses sensitive to triple gauge couplings are electroweak Z production and many diboson processes ($W^+W^-$, $W^{\pm}Z$, $ZZ$, $W^{\pm}\gamma$, and $Z\gamma$). In addition, $\gamma\gamma \rightarrow W^+W^-$ production, $WV\gamma$ production, where $V=W,Z$, and $W^{\pm}W^{\pm}jj$ production are presented as probes of quartic gauge couplings.
