The measurement uses a sample of proton-proton collisions at root s = 8TeV, collected during a special low-luminosity running that corresponds to an integrated luminosity of 18: 4 +/- 0: 5 pb(-1). The production of W bosons is studied in both electron and muon decay modes, while the production of Z bosons is studied using only the dimuon decay channel. The ratios of W- to W+ and Z to W di ff erential cross sections are also measured. The measured di ff erential cross sections and ratios are compared with theoretical predictions up to next-to-next leading order in QCD.eninfo:eu-repo/semantics/openAccessHadron-Hadron scattering (experiments)QCDArticle2WOS:0003976475000012-s2.0-8501348753510.1007/JHEP02(2017)096Q1Q1
