Diboson production cross section at LHC

This paper presents an overview of the diboson production cross-section measurements and constraints on anomalous triple-gauge boson couplings performed by the ATLAS and CMS collaborations using proton-proton collisions produced at a centre-of-mass energy of $\sqrt{s}$ = 7 and 8 TeV at LHC. Results for all combinations of $W, Z$ and $\gamma$ gauge bosons (excluding $\gamma\gamma$) are presented with emphasis on the new $WZ$ and $ZZ$ production cross sections measured by ATLAS at $\sqrt{s}$ = 8 TeV and on the new constraints on anomalous triple-gauge couplings set by CMS in the $WW$ and $Z\gamma$ modes.
