Trigger-Level Analysis at ATLAS

Abstract
The ATLAS Collaboration recently released its full Run-2 dijet Trigger-Level Analysis (TLA), which processes an unprecedented dataset of more than 60 billion events within a single analysis. By reconstructing jets directly in the high-level trigger, TLA achieves a data-taking rate more than twenty times higher than the nominal ATLAS readout. This approach enables searches for new physics in dijet final states that would otherwise be limited by data-acquisition bandwidth. While conventional LHC dijet searches are typically restricted to masses above 1 TeV, the presented analysis extends the accessible mass range down to 375 GeV. As a result, the presented analysis sets world-leading exclusion limits for simplified dark matter models.
