Abstract
Results are presented from a search in the dijet final state for new massive narrow resonances decaying to pairs of and bosons or to a boson and a quark. Results are based on data recorded in proton-proton collisions at with the CMS detector at the CERN LHC. The data correspond to an integrated luminosity of . The mass range investigated extends upwards from 1.2 TeV. No excess is observed above the estimated standard model background and limits are set at 95% confidence level on cross sections, which are interpreted in terms of various models that predict gravitons, heavy spin-1 bosons, and excited quarks. In a heavy vector triplet model, and resonances, with masses below 3.2 and 2.7 TeV, respectively, and spin-1 resonances with degenerate masses below 3.8 TeV are excluded at 95% confidence level. In the case of a singlet resonance masses between 3.3 and 3.6 TeV can be excluded additionally. Similarly, excited quark resonances, , decaying to and with masses less than 5.0 and 4.7 TeV, respectively, are excluded. In a narrow-width bulk graviton model, upper limits are set on cross sections ranging from 0.6 fb for high resonance masses above 3.6 TeV, to 36.0 fb for low resonance masses of 1.3 TeV.
