Measurements of the W±→ℓ±ν and Z→ℓ+ℓ− production cross sections (where ℓ±=e±,μ±) in proton-proton collisions at s√=13 TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb−1 The total inclusive W±-boson production cross sections times the single-lepton-flavour branching ratios are σtotW+=11.83±0.02(stat)±0.32(sys)±0.25(lumi) nb and σtotW−=8.79±0.02(stat)±0.24(sys)±0.18(lumi) nb for W+ and W−, respectively.
