Description

Precise reconstruction of charged-particle trajectories is critical for unlocking the full physics potential of modern high energy physics experiments. Pushing experiments to the intensity and luminosity frontiers results in increasing data rates, bringing existing approaches to their limits. ACTS (A Common Tracking Software) provides a high-performance, experiment-independent toolkit that combines detailed detector geometry, accurate particle propagation in complex magnetic fields, and advanced algorithms for seeding, track finding, and fitting.

The modular design of ACTS enables adaptation to a wide range of detector concepts across high-energy physics, including applications in environments such as the ATLAS at the High-Luminosity LHC and sPhenix at the Relativistic Heavy Ion Collider, as well as detector upgrade and feasibility studies. Ongoing developments position ACTS as an R&D testbed for highly parallelised track reconstruction and the integration of modern ML/AI approaches, driving the evolution of tracking towards robust, portable, and high-throughput solutions for next-generation experiments.
