Abstract

Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at sqrt(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 -> e nu, mu nu or Z -> e+ e-, mu+ mu-, or nu (nu)over-bar). 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, sigma(pp -> WZ) = 30.7 +/- 9.3 (stat.) +/- 7.1 (syst.) +/- 4.1 (th.) +/- 1.0 (lum.) pb and sigma(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.
