Abstract (data abstract)
CERN-LHC. 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 sqrt(s) = 2.76 TeV. The decay channels W->lnu 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: sigma_tot(W^+ -> lnu) = 2312 ± 26(stat.) ± 27(syst.) ± 72(lumi.) ±30 (extr.)pb, sigma_tot(W^- -> lnu) = 1399 ± 21(stat.) ± 17(syst.) ± 43(lumi.) ±21 (extr.)pb, sigma_tot(Z -> ll) = 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. W-boson fiducial region is defined as: - ptLepton > 20 GeV - |etaLepton| < 2.4 - MET > 25 GeV - mT > 40GeV Z-boson fiducial region is defined as: - ptLepton > 20 GeV - |etaLepton| < 2.4 - 66 < |mll| < 116 GeV
