Search for new physics in the dijet mass distribution using 1 fb<sup>-1</sup> of pp collision data at √s = 7 TeV collected by the ATLAS detector

Invariant mass distributions of jet pairs (dijets) produced in LHC proton–proton collisions at a centre-ofmass energy √s = 7 TeV have been studied using a data set corresponding to an integrated luminosity of 1.0 fb<sup>-1</sup> recorded in 2011 by ATLAS. Dijet masses up to ∼4 TeV are ob...

description Invariant mass distributions of jet pairs (dijets) produced in LHC proton–proton collisions at a centre-ofmass energy √s = 7 TeV have been studied using a data set corresponding to an integrated luminosity of 1.0 fb<sup>-1</sup> recorded in 2011 by ATLAS. Dijet masses up to ∼4 TeV are observed in the data, and no evidence of resonance production over background is found. Limits are set at 95% C.L. for several new physics hypotheses: excited quarks are excluded for masses below 299 TeV, axigluons are excluded for masses below 3.32 TeV, and colour octet scalar resonances are excluded for masses below 1.92 TeV.
