The invariant mass distributions of dijet events produced in pp collisions at a center of mass energy of 8 TeV by the LHC has been studied using the ATLAS detector. A total integrated luminosity of 13.0 fb−1 collected in 2012 has been employed. The observed dijet masses extend up to 4.69 TeV. No local excesses have been observed. A 95% C.L. limit on the production of a benchmark model of excited quarks, q*, has been set at 3.84 TeV. The previous ATLAS 95% C.L. limit on q* mass using 5.8 fb−1 of 2012 data was set at 3.66 TeV. Limits on cross section times acceptance, σ×A, have also been updated using simplified gaussian models in order to allow limit setting on new theories.
