Sumario:The study of the diboson production characteristics with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at ps up to 8 TeV allows for the first time to measure the behaviour of the electroweak interactions in an unexplored energy range. This measurement not only verifies the Standard Model theory but also aims for new Physics searches by probing possible anomalous coupling at the triple gauge-boson vertices. Besides, the SM W+W- and ZZ productions are irreducible backgrounds for searches of the Higgs boson in the diboson decay channels. The measurements of diboson production in ATLAS are presented for di erent electroweak diboson channels: ZZ, WZ, WW , Wgamma and Zgamma. Anomalous triple-gauge coupling limits that are obtained from these measurements are also presented.
