Sažetak
A search is reported for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ). The analysis is performed on an inclusive sample of multijet events corresponding to an integrated luminosity of 19.7 fb−1 , collected in proton-proton collisions at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. The search uses novel jet- substructure identification techniques that provide sensitivity to the presence of highly boosted vector bosons decaying into a pair of quarks. Exclusion limits are set at a confidence level of 95% on the production of: (i) excited quark resonances q∗ decaying to qW and qZ for masses less than 3.2 TeV and 2.9 TeV, respectively, (ii) a Randall-Sundrum graviton GRS decaying into WW for masses below 1.2 TeV, and (iii) a heavy partner of the W boson W0 decaying into WZ for masses less than 1.7 TeV. For the first time mass limits are set on W0 → WZ and GRS → WW in the all-jets final state. The mass limits on q∗ → qW, q∗ → qZ, W0 → WZ, GRS → WW are the most stringent to date. A model with a “bulk” graviton Gbulk that decays into WW or ZZ bosons is also studied.
