Measurements of the production cross section of pairs of electroweak gauge bosons at the LHC constitute stringent tests of the electroweak sector of the Standard Model and provide a model-independent means to search for New Physics at the TeV scale. The ATLAS experiment at the LHC has developed a comprehensive diboson physics program to further explore this frontier. The focus of the seminar will be on precision measurements of diboson processes and searches of vector boson scattering production with the ATLAS Run2 data.
