Abstract (data abstract)
CERN-LHC. Search for localized excesses in dijet mass distributions of low-dijet-mass events produced in association with a high transverse energy photon. Two variants are presented, one which makes no jet flavour requirements and one which requires both jets to be tagged as b-jets. The observed mass distributions are consistent with multi-jet processes in the Standard Model. The data are used to set upper limits on the production cross-section for a benchmark $Z'$ model and, separately, on generic Gaussian-shaped contributions to the distributions, extending the current ATLAS constraints on dijet resonances to the mass range between 200 and 350 GeV.
