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.
