A search for new phenomena in LHC proton-proton collisions at a center-of-mass energy of √s = 8 TeV was performed with the ATLAS detector using an integrated luminosity of 17.3 fb[superscript −1]. The angular distributions are studied in events with at least two jets; the highest dijet mass observed is 5.5 TeV. All angular distributions are consistent with the predictions of the standard model. In a benchmark model of quark contact interactions, a compositeness scale below 8.1 TeV in a destructive interference scenario and 12.0 TeV in a constructive interference scenario is excluded at 95% C.L.; median expected limits are 8.9 TeV for the destructive interference scenario and 14.1 TeV for the constructive interference scenario.
