Title: Measurement of WZ and ZZ production in pp collisions at $$\sqrt{s} = 8\,\text {TeV} $$ in final states with b-tagged jets

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 $$W \to e\nu, \mu\nu$$ or $$Z \to e^+ e^-, \mu^+ \mu^-$$, or $$\nu\bar{\nu})$$. 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, $$\sigma(pp \to WZ)$$ = 30.7 $$\pm$$ 9.3 (stat.) $$\pm$$ 7.1 (syst.) $$\pm$$ 4.1 (th.) $$\pm$$ 1.0 (lum.) pb and $$\sigma(pp \to ZZ)$$ = 6.5 $$\pm$$ 1.7 (stat.) $$\pm$$ 1.0 (syst.) $$\pm$$ 0.9 (th.) $$\pm$$ 0.2 (lum.) pb, are consistent with next-to-leading order quantum chromodynamics calculations.
