LOTF

LOTF is a C++/ROOT track reconstruction algorithm designed for the Straw Tube Tracker in PANDA. If you wish to use it, please get in contact with me. This code was meant to be included in the Pandaroot reconstruction software and therefore requires several dependencies which are not public.

LOTF was published in the following paper:

• Reconstructing charged-particle trajectories in the PANDA Straw Tube Tracker using the LOcal Track Finder (LOTF) algorithm

Paper summary

LOTF is a fast and robust track reconstruction algorithm optimized for the PANDA Straw Tube Tracker. It uses:

• A graph-based representation of the STT geometry
• A three-phase reconstruction approach: connect, fit, and merge
• A system of virtual nodes to recover z-information from skewed layers
• A low computational complexity, achieving 68,000 hits/s without parallelization
