Fake track studies for the ATLAS TRT in high pileup scenarios — •Patrick Bauer, Klaus Desch, and Christian Grefe — Physikalisches Institut, Nussallee 12, D-53115 Bonn

The Transition Radiation Tracker (TRT) is an integral component of the inner tracking setup of the ATLAS detector at CERN. During Run 3 the increased luminosity provided by the LHC will lead to an ⟨ µ ⟩ ≥ 75 compared to ⟨ µ ⟩ ≈ 25 in 2016. Therefore it is essential to investigate the detector response and the track reconstruction performance in an high occupancy (up to 80 %) environment with large numbers of pileup tracks.
In order to ensure a optimal tracking it is important to keep the number of fake tracks caused by combining hits from different tracks (including pileup tracks) to a minimum. In this talk studies of the the fake track rates in ATLAS TRT are presented for high pileup scenarios.
