The multiboson final states allow to perform several measurements and to probe the Standard Model (SM) predictions with the amount of data collected at the LHC. Both the ATLAS and the CMS collaborations published new and interesting measurements in diboson and triboson final states selected in the Run 2 datasets corresponding to an integrated luminosity of about 139 fb−1. Signatures with fully reconstructed systems (4-leptons), with missing energy (WZ and WW+jets) and photon associated final states (Wγ and Vγγ) have been exploited. Differential cross sections have been measured and the study of other properties such as the boson polarisation or the Radiation Amplitude Zero (RAZ) effect have been performed. Furthermore, constraints of the SM properties with precision higher and higher allow to perform Beyond Standard Model (BSM) physics results in the Effective Filed Theory (EFT) framework.
