Abstract

Measurements of the and production cross sections (where ) in proton–proton collisions at 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 -boson production cross sections times the single-lepton-flavour branching ratios are and for and , respectively. The total inclusive Z-boson production cross section times leptonic branching ratio, within the invariant mass window , is . The , , 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 and . 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.
