Abstract:

A search for new particles decaying to two

\mathrm{Z}

bosons with subsequent decay to a final state containing two leptons and two quarks,

\mathrm{X}\rightarrow\mathrm{ZZ}\rightarrow\mathrm{q\bar{q}}\ell^-\ell^+

, is presented. Results are based on data corresponding to an integrated luminosity of 19.8~fb

^{-1}

of proton-proton collisions at

\sqrt{s}=8\,\text{TeV}

and collected with the CMS detector at the CERN LHC. Jet substructure techniques are exploited for separating the signal from the standard model background when the boost of the

\mathrm{Z}

causes the two quarks to merge into a single jet reconstructed in the detector. Limits on a narrow-width bulk Randall-Sundrum graviton model are set. Bulk gravitons with coupling constant

\tilde{k}=0.5

and mass smaller than

710~\,\text{TeV}

are excluded at the 95\% C.L. .
