Measurements of multi-boson production at ATLAS

Measurements of multiple electroweak bosons production at the LHC constitute an important test of the Standard Model. They are sensitive to the properties of electroweak-boson self-interactions and provide a test of the electroweak theory and of the perturbative quantum chromodynamics. In this talk, we present recent results from the ATLAS experiment for multi-boson production in proton-proton collisions at sqrt(s) =13 TeV. The differential cross-section measurement of WW production in association with jets is presented. We also present the measurement of differential cross-sections of four-lepton events, containing two same-flavour, opposite-charge electron or muon pairs.. The data are corrected for detector inefficiency and resolution and are compared to theoretical predictions. The measurements are reinterpreted in terms of an effective field theory to constrain new physics beyond the Standard Model. If available new results on other final states will be also presented.
