Recent Electroweak Results from ATLAS

ATLAS measurements of multiboson production processes involving combinations of W, Z and isolated photons are summarized. Production processes sensitive to vectorboson fusion and vectorboson scattering such as electroweak production of single vector boson associated with two forward jets and the diboson production at 8 TeV pp collisions are also presented and compared to Standard Model expectations. A measurement of the cross section and branching fraction for Z> 4 leptons are presented and are found consistent with the expectation from the Standard Model. Measurements of Standard Model parameters are performed with high precision by ATLAS, such as the weak mixing angle, and are compared to world averages.
