Abstract

Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at√s = 8 TeV in final states where one Z boson decays to b-tagged jets. The other gauge boson, either W or Z, is detected through its leptonic decay (either W → eν, μν or Z → e+e, μ+μ, or νν‾). The results are based on data corresponding to an integrated luminosity of 18.9 fb−1 collected with the CMS detector at the Large Hadron Collider. The measured cross sections, σ(pp → WZ) = 30.7 ± 9.3 (stat.) ±7.1 (syst.) ± 4.1 (th.) ± 1.0 (lum.) pb and σ(pp → ZZ) = 6.5 ± 1.7 (stat.) ± 1.0 (syst.) ± 0.9 (th.) ± 0.2 (lum.)pb, are consistent with next-to-leading order quantum chromodynamics calculations.
