The results are based on 2250 W -> lnu and 179 Z/gamma* -> ll candidate events selected from a data set corresponding to an integrated luminosity of approximately 320 nb-1. The measured total W and Z/gamma*-boson production cross sections times the respective leptonic branching ratios for the combined electron and muon channels are sigma_W^tot * BR(W -> lnu) = 9.96 +- 0.23(stat) +- 0.50(syst) +- 1.10(lumi) nb and sigma_Z/gamma*^tot * BR(Z/gamma* -> ll) = 0.82 +- 0.06(stat) +- 0.05(syst) +- 0.09(lumi) nb (within the invariant mass window 66 < m_ll < 116 GeV). The W/Z cross-section ratio is measured to be 11.7 +- 0.9(stat) +- 0.4(syst). In addition, measurements of the W+ and W- production cross sections and of the lepton charge asymmetry are reported. Theoretical predictions based on NNLO QCD calculations are found to agree with the measurements.     Numerical values supplied by M Vincter.\n\nUPDATE 06/04/2016: The tables detailing results on total cross sections had misleading phase space selections quoted, these are removed now.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.56744.v1/t1","@type":"Dataset","description":"Measured fiducial cross section times leptonic branching ratio for W+ production in the W+ -> e+
