A search for new physics in dijet mass and angular distributions in ppcollisions at √s=7 TeV measured with the ATLAS detector
A search for new interactions and resonances produced in LHC proton-proton (pp) collisions at a centre-of-mass energy √s = 7 TeV was performed with the ATLAS detector. Using a dataset with an integrated luminosity of 36 pb -1 , dijet mass and angular distributions were measured up to dijet masses of...
