Search for new phenomena in photon + jet events collected in proton-proton collisions at √s = 8 TeV with the ATLAS detector
This Letter describes a model-independent search for the production of new resonances in photon + jet (γ + jet) events using 20 fb -1 of proton-proton LHC data recorded with the ATLAS detector at a centre-of-mass energy of √s = 8 TeV. The γ + jet mass distribution is compared to a background model f...
