Search for resolved dijet resonances produced in association with a photon

Otro; ATLAS Conference Note; 2018

This note describes a new search for low mass dijet resonances produced in association with a high pt photon. The search uses the full 2015--2017 datasets collected by ATLAS at s√=13TeV. Two cases are considered in the analysis: an inclusive selection and a selection requiring that the two jets from the candidate resonance are both tagged as b-jets. A smoothly falling background estimate is produced via a sliding window fit and the differences between the data and fit will be examined for evidence of new physics. The results will be used to set limits on a benchmark Z′model as well as on a generic Gaussian shape.
