Measurement of the inclusive W$^{\pm}$ and Z/$\gamma^∗$ cross sections in the e and mu decay channels in p-p collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector

Measurements by the ATLAS Collaboration are presented of the inclusive Drell-Yan W+- to lnu and Z/gamma∗ to ll (l = e,mu) production cross sections in proton-proton collisions at sqrt{s}= 7 TeV. The cross sections are measured 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 per cent. The integrated and the differential W+- and Z/gamma∗ cross sections in the e and mu channels are combined, and compared with perturbative QCD calculations, based on a number of different parton distribution sets available at NNLO.
