Abstract

A study into the impact of quark-gluon tagging on a dijet search was performed using
simulated dijet invariant mass spectra from the ATLAS detector. Monte Carlo simulations
were compared to data from the 2015-2018 data taking periods. The analysis covered a mass range between 2 TeV and 7 TeV and found improvements to the expected 95% CL upper mass limits for a singlet scalar model decaying to a gluon-gluon final state in the region of ∼30% at 4.5 TeV compared to an untagged search. Improvements to an excited quark model of ∼10% were obtained for a mass above 6 TeV.
