High-precision measurements by the ATLAS Collaboration are presented of inclusive $W^+\\to\\ell^+\\nu$, $W^-\\to\\ell^-\\bar{\\nu}$ and $Z/\\gamma^*\\to\\ell\\ell$ ($\\ell=e,\\mu$) Drell--Yan production cross sections at the LHC.  The data were collected in proton--proton collisions at $\\sqrt{s} = 7$ TeV with an integrated luminosity of 4.6 fb$^{-1}$. Differential $W^+$ and $W^-$ cross sections are measured in a lepton pseudorapidity range $|\\eta_{\\ell}| = 2.5$. Differential $Z/\\gamma^*$ cross sections are measured as a function of the absolute dilepton rapidity, for $|y_{\\ell\\ell}| < 3.6$, for three intervals of dilepton mass, $m_{\\ell\\ell}$, extending from 46 to 150 GeV. The integrated and differential electron- and muon-channel cross sections are combined and compared to theoretical predictions using recent sets of parton distribution functions. The data, together with the final inclusive $e^{\\pm}p$ scattering cross-section data from H1 and ZEUS, are interpreted in a  next-to-next-to-leading-order QCD analysis, and a new set of parton distribution functions, ATLAS-epWZ16, is obtained. The ratio of strange-to-light sea-quark densities in the proton is determined more  accurately than in previous determinations based on collider data only, and is established to be close to unity in the sensitivity range  of the data. A new measurement of the CKM matrix element $|V_{cs}|$ is also provided. The differential cross sections are provided in two forms, a version with summarised uncertainties as in the paper tables and as \"attached resource\" files in HerAverager/xFitter format detailing all sources of correlated uncertainties separately. In addition to the experimental results, detailed information on the theoretical predictions are provided as required to reproduce the interpretation.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t1","@type":"Dataset","description":"Fiducial cross sections times branching ratios for $W^+$, $W^-$, central and forward $Z/\\gamma^*$ ($m_{ee} = 66-116$ GeV) production in the...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t2","@type":"Dataset","description":"Fiducial cross sections times branching ratios for $W^+$, $W^-$ and $Z/\\gamma^*$ ($m_{\\mu\\mu} = 66-116$ GeV) production in the muon decay...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t3","@type":"Dataset","description":"Integrated fiducial cross sections times leptonic branching ratios in the electron and muon channels and their combination with statistical and...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t4","@type":"Dataset","description":"Ratios of integrated fiducial CC and NC cross sections obtained from the combination of electron and muon channels with statistical...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t5","@type":"Dataset","description":"Total cross sections times leptonic branching ratios obtained from the combination of electron and muon channels with statistical and systematic...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t6","@type":"Dataset","description":"Ratios of total CC and NC cross sections obtained from the combination of electron and muon channels with statistical and...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t7","@type":"Dataset","description":"The correlation coefficients of the $W^+$, $W^-$ and $Z$ fiducial cross-section measurements.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.76541.v1/t8","@type":"Dataset","description":"Measurement of the electron-to-muon cross-section ratios for the $W$ and $Z$ production, $R_W$ and $R_Z$.
