Multi-boson production at ATLAS and CMS

We present studies on production of pairs or triplets of gauge bosons in proton-proton collisions at 8 and 13 TeV center-of-mass energies, using data from the ATLAS and CMS experiments. Results are given as inclusive and differential cross-sections, from which constraints on anomalous triand quadri-linear gauge couplings are extracted, with specific focus on the most recent results from the two collaborations.
