Sumario:The production of the W and Z bosons is the standard candle process at the LHC. Measurement of the transverse momentum of the Z boson performed by the ATLAS collaboration is reported for sqrt{s} = 7 TeV. The measurement is sensitive to soft resummation effects for small momentum transfers and to multiple hard jet emissions for large momentum transfers, probing QCD in a unique way. Measurements of the Drell-Yan production at low and high invariant masses are reported and compared to predictions based on NNLO QCD corrected for electroweak effects. A measurement of the lepton forward-­backward asymmetry for Z/gamma* production is used to determine the weak mixing angle. A measurement of the cross section for 4 lepton production near the Z resonance is presented for sqrt{s} = 7 and 8 TeV proton­-proton collisions recorded with the ATLAS experiment. An overview of these results is given.
