New High-Performance Tracking in a High-Multiplicity Environment at NA61/SHINE

Effective tracking software is an essential component of any tracking detector based high-energy physics experiment. Most tracking software is optimized for the particular experiment using it, resulting in a fast and robust framework that performs very well in specific data-taking conditions. At CERN's NA61/SHINE experiment, a variety of data-taking conditions must be handled. Collisions probing QCD interactions can create thousands of primary and secondary tracks that must be reconstructed, while collisions for studying neutrino production might create only one or two tracks. The tracking software must be able to handle these vastly different environments in a robust way.
The talk will detail the recently-developed SHINE tracking software, a fast and efficient tracking framework based on the Cellular Automaton algorithm for track seeding.
