Query: Measurement of the inclusive W+- and Z/gamma cross sections in the
  electron and muon decay channels in pp collisions at sqrt(s) = 7 TeV with the
  ATLAS detector   The production cross sections of the inclusive Drell-Yan processes W to l nu
and Z/gamma to ll (l=e,mu) are measured in proton-proton collisions at sqrt(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
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.
