A Tracking Algorithm for Straw Tube Trackers Based on a Cellular Automaton*

The MUon Scattering Experiment (MUSE) takes place at the Paul Scherrer Institute (PSI) and is designed to address the proton radius puzzle by simultaneously measuring the proton radius through both e^±p and μ^±p elastic scattering, using the PiM1 secondary beam line. The MUSE apparatus incorporates a large-acceptance, non-magnetic detector system. The Straw Tube Tracker (STT) detector is designed to measure the trajectories of the scattered particles for further scattered event reconstruction.

An advanced tracking software is crucial for reliable event reconstruction and further physics analysis. In this presentation, an overview of the new tracking algorithm based on the cellular automaton method, customized for MUSE detector geometry is presented. The details of the algorithm and encountered challenges will be discussed.
