Abstract

Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at = 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 or , or . The results are based on data corresponding to an integrated luminosity of 18.9 inverse-femtobarns collected with the CMS detector at the Large Hadron Collider. The measured cross sections, = 30.7 9.3 (stat.) 7.1 (syst.) 4.1 (th.) 1.0 (lum.) pb and = 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.
