Search for New Phenomena in the Dijet Mass Distribution updated using 13.0 fb−1 of pp Collisions at √s = 8 TeV collected by the ATLAS Detector

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 loc...
