Abstract

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 σ_W⁺^tot=11.83±0.02 (stat)±0.32 (sys)±0.25 (lumi) nb and σ_W⁻^tot=8.79±0.02 (stat)±0.24 (sys)±0.18 (lumi) nb for W⁺ and W⁻, respectively. The total inclusive Z-boson production cross section times leptonic branching ratio, within the invariant mass window 66<m_ℓℓ<116 GeV, is σ_Z^tot=1.981±0.007 (stat)±0.038 (sys)±0.042 (lumi) nb. The W⁺, W⁻, and Z-boson production cross sections and cross-section ratios within a fiducial region defined by the detector acceptance are also measured. The cross-section ratios benefit from significant cancellation of experimental uncertainties, resulting in σ_W⁺^fid/σ_W⁻^fid=1.295±0.003 (stat)±0.010 (sys) and σ_W^±^fid/σ_Z^fid=10.31±0.04 (stat)±0.20 (sys). Theoretical predictions, based on calculations accurate to next-to-next-to-leading order for quantum chromodynamics and to next-to-leading order for electroweak processes and which employ different parton distribution function sets, are compared to these measurements.
