Sumario:A search for a Randall-Sundrum Kaluza-Klein graviton decaying to two $Z$ bosons with subsequent decay to a final state containing two leptons and two jets, $\mathrm{G}^{*}\rightarrow \mathrm{ZZ}\rightarrow \mathrm{q\bar{q}}\ell^-\ell^+$ is presented. Results are based on data corresponding to an integrated luminosity of 4.9~fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=7\,\text{Te\hspace{-.08em}V}$ collected with the CMS detector at the CERN LHC. Selections to discriminate between signal and background events are based on kinematic and topological quantities including the angular spin correlations of the decay products. No evidence for a graviton is found and upper limits on the production cross section are set in the range of masses between 400~GeV and 1000~GeV.
