Track Reconstruction with the FASER detector with ACTS — Florian Bernlochner, Jochen Dingfelder, Markus Prim, and •Tobias Böckh — Physikalisches Institut der Rheinischen Friedrich-Wilhelms-Universität Bonn

The Faser (ForwArd Search ExpeRiment) experiment is located 480m downstream from the ATLAS interaction point at the LHC and is designed to search for light, weakly interacting particles. One of the main goals is the search for a massive dark photon that decays into two charged particles. This requires a good hit resolution and tracking performance to effectively separate the two closely-spaced, oppositely-charged tracks. In this talk, we will summarize the track reconstruction of FASER, which is based on the experiment-independent toolkit for charged particle track reconstruction ACTS. We will also show first results of the hit resolution with cosmic data and briefly recap the status of the experiment.
