Di-boson results at ATLAS

Pairs of gauge boson produced in proton-proton collisions at a center-of-mass energy root s of 7 TeV are reconstructed with the ATLAS detector in their leptonic final states. Based on samples of integrated luminosity L = 1.0 fb(-1) (for WW, WZ and ZZ) and 35 pb(-1) (for W gamma and Z gamma) of 2011 and 2010 LHC data, the total di-boson production cross sections are measured. They are found, together with the kinematic distributions of the selected di-boson systems to be compatible with the expectation from the Standard Model. The di-boson production also gives a handle on possible anomalous triple gauge boson couplings, for which 95% confidence limits are set.
