The production cross-sections for W± and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb−1 collected at a centre-of-mass energy √s=2.76 TeV. The decay channels W→ℓν and Z→ℓℓ are used, where ℓ can be an electron or a muon. The cross-sections are presented for a fiducial region defined by the detector acceptance and are also extrapolated to the full phase space for the total inclusive production cross-section. The combined (average) total inclusive cross-sections for the electron and muon channels are: σtotW+→ℓν=σtotW−→ℓν=σtotZ→ℓℓ=2312±26 (stat.)±27 (syst.)±72 (lumi.)±30 (extr.) pb,1399±21 (stat.) ±17 (syst.)±43 (lumi.)±21 (extr.) pb,323.4±9.8 (stat.)±5.0 (syst.)±10.0 (lumi.)±5.5(extr.) pb.Measured ratios and asymmetries constructed using these cross-sections are also presented.
