Measurement of the inclusive W± and Z/γ* cross sections in the e and μ decay channels in pp collisions at √s=7 TeV with the ATLAS detector
The production cross sections of the inclusive Drell-Yan processes W[superscript ±]→ℓν and Z/γ*→ℓℓ (ℓ=e, μ) are measured in proton-proton collisions at √s=7 TeV with the ATLAS detector. The cross sections are reported integrated over a fiducial kinematic range, extrapolated to the full range, and a...

| Summary: | The production cross sections of the inclusive Drell-Yan processes W[superscript ±]→ℓν and Z/γ*→ℓℓ (ℓ=e, μ) are measured in proton-proton collisions at √s=7 TeV with the ATLAS detector. The cross sections are reported integrated over a fiducial kinematic range, extrapolated to the full range, and also evaluated differentially as a function of the W decay lepton pseudorapidity and the Z boson rapidity, respectively. Based on an integrated luminosity of about 35 pb-1 collected in 2010, the precision of these measurements reaches a few percent. The integrated and the differential W[superscript ±] and Z/γ* cross sections in the e and μ channels are combined, and compared with perturbative QCD calculations, based on a number of different parton distribution sets available at next-to-next-to-leading order. |
