Description
FASER-2 is a potential upgrade to the FASER experiment, and could be hosted in the proposed Forward Physics Facility (FPF) 620m to the west of the ATLAS interaction point, in the far-forward region of the LHC collisions. The experiment would have sensitivity for long-lived particles (LLPs) produced by rare meson decays that could be potential candidates for light dark matter. The proposed upgrade involves a significantly enlarged volume compared to FASER, resulting in an increase in reach for various BSM signals of several orders of magnitude and allows sensitivity to models that were previously out of reach, such as Dark Higgs and Heavy Neutral Leptons. This poster will present the development of a tracking software for the FASER-2 experiment using the A Common Tracking Software (ACTS) toolkit to aid in accurate mass and pointing reconstruction of charged particles. The developed tracking software will be used to compare various FASER-2 layouts and tracker technologies, thereby contributing to the design studies of the FASER-2 experiment.
