Precision measurements with W and Z/gamma* bosons with the ATLAS detector

The inclusive production of single W and $Z/\gamma^{*}$ bosons are standard candles at hadron colliders. ATLAS has recently completed a set of very precise measurements of production cross-sections and lepton decay angular distributions integrated and differential in several variables at centre-of-mass energies of 7, 8, and 13 TeV. ATLAS has performed a measurement of the complete set of coefficients that describe the angular distributions of the decay leptons in Z events in fine bins of the Z transverse momentum and in several bins of Z rapidity. Furthermore a measurement of the dilepton transverse momentum spectrum as well as the related angular decorrelation variable $\phi^{*}$ was performed in a wide range of dilepton masses from 12 to 150 GeV. Precise double-differential measurements of the Drell-Yan cross section in the region above the Z peak up to dilepton masses of 1500 GeV are presented as well. Finally, first precise measurements of integrated W and Z cross sections and cross section ratios at 13 TeV are reported. All results are compared to higher-order QCD calculations at up to NNLO and state-of-the-art Monte Carlo simulations and provide stringent tests of the limitations of these calculations. These measurements can be used to constrain the parton densities of the proton, in particular in the quark and photon sectors. They also provide stringent tests of resummation effects and hard emissions for small and large boson momenta, respectively.
