Measurement of W± and Z-boson production cross sections in pp collisions at √s=13 TeV with the ATLAS detector

Journal Article (Journal Article)

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 . The total inclusive W -boson production cross sections times the single-lepton-flavour branching ratios are σ =11.83±0.02 (stat)±0.32 (sys)±0.25 (lumi) nb and σ =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<116 GeV, is σ =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 /σ =1.295±0.003 (stat)±0.010 (sys) and σ /σ =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. ± ± + − ± ± ± −1 ± + tot − tot + − tot + − + fid − fid ± fid fid W W ℓℓ Z W W W Z
