A Novel Segment-Based Tracking Algorithm for HLT under High-Occupancy and Complex Conditions

Changqing Feng, Hang Zhou, Jianbei Liu, Pengkun Jia, Yuhe Huang, Zhujun Fang

A segment-based algorithm with 11 pre-defined patterns reduces global tracking elements to 400-500 at 25% occupancy in gaseous detectors.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

With the depth-first search within connected components, the simulation results show that the algorithm maintains stable performance with occupancy ranging from 5% to 25%, achieving a data compression ratio of approximately 50% to 70%.

C2weakest assumption

The 11 pre-defined patterns together with position-momentum-timing criteria for edge-matrix formation and stereo superlayer merging are sufficient to capture relevant tracks without significant efficiency loss under high-occupancy conditions.

C3one line summary

A new segment-based HLT tracking algorithm using 11 patterns and optimized edge matrices reduces global tracking complexity to 400-500 elements at 25% occupancy with 50-70% data compression.
