Measurement of $ \mathrm{ W^+ W^- } $ and ZZ production cross sections in pp collisions at $\sqrt{s}$ = 8 TeV
Phys. Lett. B 721 (2013) 190
Abstract: The W+W- and ZZ production cross sections are measured in proton-proton collisions at $\sqrt{s}$ = 8 TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up to 5.3 inverse femtobarns. The measurements are performed in the leptonic decay modes W+W- to l' nu l' nu and ZZ to 2l 2l', where l = e, mu and l' = e, mu, tau. The measured cross sections sigma(pp to W+W-) = 69.9 +/- 2.8 (stat.) +/- 5.6 (syst.) +/- 3.1 (lumi.) pb and sigma(pp to ZZ) = 8.4 +/- 1.0 (stat.) +/- 0.7 (syst.) +/- 0.4 (lumi.) pb, for both Z bosons produced in the mass region 60 $\lt m_Z \lt$ 120 GeV, are consistent with standard model predictions. These are the first measurements of the diboson production cross sections at $\sqrt{s}$ = 8 TeV.
