Abstract
Measurements of single W and Z as well as diboson WW, WZ and ZZ production at the LHC performed by the ATLAS Collaboration in 2010 and 2011 are presented. The data provide accurate tests of the theory in a wide kinematic range. A QCD analysis of the W and Z boson differential distributions reveals a novel sensitivity to the strange-quark density which is found to be large compared to previous expectations. Studies of W + b and Z + b jet production and W polarisation test NLO QCD calculations and proton PDFs. The diboson cross section measurements are used to determine limits on the anomalous couplings. No deviation from the Standard Model is observed.
