Abstract : The first measurement of the production cross‐sections for W and Z bosons in proton‐proton interactions at sqrt(s) = 7 TeV are reported from the ATLAS experiment. Based on its excellent capability for reconstructing both high pT electrons and muons, the electron and the muon decay modes of the W/Z bosons are compared. First results for the ratio of W/Z production and of W+/W‐ production will also be described.
