Measurements are presented of fiducial and total inclusive cross sections for W-plus, W-minus, and Z bosons, decaying to leptonic or muonic final states, in proton-proton collisions at 13 TeV center-of-mass energies, using the ATLAS Detector at CERN's Large Hadron Collider. Data used in these measurements correspond to 81 inverse picobarns of integrated luminosity, recorded during June and July 2015. Cross sections are measured in six independent analysis channels, corresponding to the electronic and muonic final states of W-plus, W-minus, and Z bosons. Electron and muon channels are combined to obtain fiducial and total cross-sections-times-leptonic-branching-ratios for each of W-plus, W-minus, and Z. Lepton universality ratios for W and Z are calculated and found to be compatible with Standard Model expectations and global averages. The ratio of W and Z fiducial cross sections is measured. The ratio of W-plus and W-minus fiducial cross sections is measured. All measurements are compared to NNLO(QCD)+NLO(EW) predictions, based on a selection of modern proton parton distribution functions.

The QCD corrections to W production associated with a jet are studied using the ratio of W + 1 Jet to W + 0 Jets cross sections for a jet with a transverse energy of 25 GeV. The measured ratio of $0.096\pm0.005\sp{stat}\pm0.008\sp{syst}$ is significantly higher than the theoretical predictions of Giele et al. of 0.053. This discrepancy is at least partly due to the relatively unconstrained gluon distribution of the proton.

Recent results of W[gamma], Z[gamma] and WW cross-section measurements in the electron and muon channels are reported from p[bar p] collisions at [radical]s = 1.96 TeV recorded by the CDF and D0 collaborations. Total cross-sections and kinematic distributions are found to be consistent with Standard Model expectations.

A preliminary measurement of the ratio, R1°, of the production cross sections for W + 1 Jet and W + 0 Jets processes at (square root)s = 1800 GeV by the D0 Collaboration is presented. A comparison of this ratio is made to next-to-leading order calculations and the implications of these comparisons are discussed.

A measurement of inclusive W and Z production cross sections in pp collisions at sqrt(s)=7 TeV is presented. The electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns. The measured inclusive cross sections are sigma(pp-> WX) B(W-> l nu) = 10.30 +/- 0.02 (stat.) +/- 0.10 (syst.) +/- 0.10 (th.) +/- 0.41 (lumi.) nb and sigma(pp -> ZX) B(Z-> l+̂l-̂) = 0.974 +/- 0.007 (stat.) +/- 0.007 (syst.) +/- 0.018 (th.) +/- 0.039 (lumi.) nb, limited to the dilepton invariant mass range 60 to 120 GeV. The luminosity-independent cross section ratios are [sigma(pp->WX) B(W-> l nu)]/[sigma(pp-> ZX) B(Z->l+̂l-̂)] = 10.54 +/- 0.07 (stat.) +/- 0.08 (syst.) +/- 0.16 (th.) and [sigma(pp->W+̂X) B(W+̂ -> l+̂nu)] / [sigma(pp->W-̂ X) B(W-̂ -> l-̂ nu)] = 1.421 +/- 0.006 (stat.) +/- 0.014 (syst.) +/- 0.029 (th.). The measured values agree with next-to-next-to-leading order QCD cross section calculations based on recent parton distribution functions.
