The ATLAS Forward Feature Extractor for the HL-LHC — •Adrian Alvarez Fernandez, Stefan Tapprogge, Ulrich Schaefer, Bruno Bauss, Julian Blumenthal, Marcel Weirich, and Dennis Layh — Johannes Gutenberg University (Mainz)

The ATLAS detector will undergo many upgrades to account for the more challenging running conditions of the High Luminosity LHC (HL-LHC). Some of these Phase-II upgrades will be focused on improving the trigger system, a crucial part to deal with the higher data rates and increased pile-up. Phase-I upgrades for Run 3 introduced the Feature EXtractors for a more refined processing of the calorimeter information and to better discriminate between jets, photons, electrons and taus. A Forward Feature EXtractor (fFEX) is being developed for the HL-LHC that will provide more flexible algorithms for the objects in the forward region (|eta|>2.5 for electrons/photons and |eta|>3.2 for jets). In contrast to the first level calorimeter trigger before HL-LHC, this system will have access to the full detailed calorimeter granularity in that region. The preliminary design of the fFEX has been recently reviewed and will be discussed in this presentation.
