We compare the photon + jet mass distribution to a background model derived from data and find consistency with the background-only hypothesis. Given the lack of evidence for a signal, we set 95% credibility level limits on generic Gaussian-shaped signals and on a benchmark excited-quark (q*) model, excluding 2 TeV Gaussian resonances with cross section times branching fraction times acceptance times efficiency near 5 fb and excluding q* masses below 2.46 TeV, respectively. %R 10.1103/PhysRevLett.108.211802 %U http://arxiv.org/abs/1112.3580 %U https://doi.org/10.1103/PhysRevLett.108.211802 %P 211802 - 18pp
