The data sample corresponds to an integrated luminosity of 2.7 fb(-1). The vector resonance is produced at large transverse momenta, with its decay products merged into a single jet. The resulting signature is a peak over background in the distribution of the invariant mass of the jet. The results are interpreted in the framework of a leptophobic vector resonance and no evidence is found for such particles in the mass range of 100-300 GeV. Upper limits at 95% confidence level on the production cross section are presented in a region of mass-coupling phase space previously unexplored at the LHC. The region below 140 GeV has not been explored by any previous experiments.eninfo:eu-repo/semantics/openAccessDijet Angular-DistributionsContact InteractionsPp CollisionsSpectrumCompositenessBosonsArticle1191110.1103/PhysRevLett.119.111802289492102-s2.0-85030156494Q1WOS:000410897100001Q1
