DOWNLOAD EBOOKI present a measurement of the W±Z production cross section in the leptonic final states in pp collisions at √s = 7 TeV and limits on anomalous trilinear gauge couplings, using 4.64 fb-1 of data collected using the ATLAS experiment at the LHC. The production cross section has been determined to be 19.0+1.4-1.3(stat.)±0.9(syst.)±0.4(lumi.) pb, in agreement with the Standard Model (SM) expectation of 17.6+1.1-1.0 pb. A search for anomalous trilinear gauge couplings has been conducted and limits have been set at the 95% confidence level; the result is consistent with the SM couplings.
