Abstract

A track reconstruction method based on a constrained combinatorial search for track candidates, i.e. combinations of detector hits possibly belonging to a track, is presented. The algorithm has been implemented as a Vector Finder software toolkit containing a track reconstruction procedure and tools to determine hit acceptance windows (a priori constraints) for the track search. Track reconstruction results for high multiplicity simulated events (∼1000 particles in the detector acceptance) are shown demonstrating good performance of the approach proposed.

摘要

提出一种基于约束组合搜索轨道候选的轨道重建方法，即可能属于轨道的检测器命中的组合。该算法已实现为Vector Finder软件工具包，其中包含轨道重建程序和确定用于轨道搜索的命中接受窗口（先验约束）的工具。高重复性模拟事件（检测器接受了约1000个粒子）的航迹重建结果显示了该方法的良好性能。
