• The production cross-sections for [Formula omitted] and Z bosons are measured using ATLAS data corresponding to an integrated luminosity of 4.0 pb [Formula omitted] collected at a centre-of-mass energy [Formula omitted] TeV. The decay channels [Formula omitted] and [Formula omitted] are used, where [Formula omitted] 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: [sigma]W+[right arrow]lνtot=2312±26(stat.)±27(syst.)±72(lumi.)±30(extr.)pb,[sigma]W-[right arrow]lνtot=1399±21(stat.)±17(syst.)±43(lumi.)±21(extr.)pb,[sigma]Z[right arrow]lltot=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. These observables benefit from full or partial cancellation of many systematic uncertainties that are correlated between the different measurements.
