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^±→ℓ⁢𝜈 and 𝑍/𝛾^*→ℓ⁢ℓ (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^± 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.
