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. |
