Resumen/Abstract
Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at √ s =8TeV 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−1−1 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.
