The production cross sections of the inclusive Drell-Yan processes W AE ! ' and Z= Ã ! " (' ¼ e, ) are measured in proton-proton collisions at ffiffi ffi s p ¼ 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 À1 collected in 2010, the

The integrated and the differential W AE and Z= Ã cross sections in the e and 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.
