Search for new physics in the dijet mass distribution using 1 fb -1 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-of-mass energy s=7 TeV have been studied using a data set corresponding to an integrated luminosity of 1.0 fb -1 recorded in 2011 by ATLAS. Dijet masses up to ~4 TeV are observed in the data, and...
