First level EM trigger algorithms in the ATLAS forward region — •Julian Fischer and Stefan Tapprogge — Institut für Physik, Johannes Gutenberg-Universität, Mainz

The HL-LHC at CERN is a planned upgrade of the Large Hadron Collider (LHC) that will increase its instantaneous luminosity of up to a factor of five in pp-collisions. In order to exploit the full potential of the HL-LHC the first level trigger of the ATLAS experiment will have to efficiently find electromagnetic objects in the forward region. A dedicated ’forward Feature EXtractor’ (fFEX) is in development for Run 4 to trigger jet and electromagnetic objects in the the ATLAS forward region making use of the full granularity of the calorimeters in pseudorapidity ranges of |η|>2.5. Two hardware modules are to be developed to cover both forward directions of the detector. This contribution will highlight the development of candidate algorithms that are designed to trigger electromagnetic objects on the fFEX modules. Performance studies will be shown and different concepts investigated to tackle the challenging geometries in this particular detector region while considering the restrictions imposed by the firmware implementation.
