Abstract:
A search for new particles decaying to two Z bosons withsubsequent decay to a final state containing two leptons and two quarks, X→ZZ→qˉqℓ−ℓ+, is presented. Results are based on data corresponding to an integrated luminosity of 19.8~fb−1 of proton-proton collisions at √s=8TeV 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 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 ˜k=0.5 and mass smaller than ~\,\text{TeV}$ are excluded at the 95\% C.L. .
