Abstract
Searches for hadronic resonances of the Dark Matter (DM) particles in the sub-TeV mass region remain as a viable target at ATLAS. However, due to the bandwidth limitation, the events that available for performing an analysis were statistically limited. Reducing the event size by recording a fraction of the full event information overcomes this limitation. An analysis that is performed on those events is called Trigger-Level Analysis(TLA). This poster highlights the TLA strategy used to search for low-mass dijet resonances. No significant excesses are found in a region between 450 and 950 GeV. As an addition, limits are set on a simplified leptophobic Z' model of DM mediator with axial coupling to quarks and DM particles as well as on Gaussian resonances.
