Measurement of W<sup>±</sup>-boson and Z-boson production cross-sections in pp collisions at √s = 2.76 TeV with the ATLAS detector
The production cross-sections for W<sup>±</sup> 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 c...

description |
The production cross-sections for W<sup>±</sup> 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:
σ<sup>tot</sup><sub>W⁺ → ℓν</sub> = 2312 ± 26 (stat.)
± 27 (syst.) ± 72 (lumi.) ± 30 (extr.) pb,
σ<sup>tot</sup><sub>W⁺ → ℓν</sub> = 1399 ± 21 (stat.) ± 17 (syst.)
± 43 (lumi.) ± 21 (extr.) pb,
σ<sup>tot</sup><sub>Z → ℓℓ</sub> = 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. |
