摘要
要实现液氩时间投影室（LArTPC）的全部科学能力，需要准确而高效的事件重建。当前及未来依赖大型LArTPC的中微子实验催生了对新思路和重建方法的需求。近年来提出的Wire-Cell是一种用于LArTPC的新型层析事件重建方法。Wire-Cell三维成像方法利用电荷、稀疏性、时间与几何信息，在模式识别之前重建电离电子的拓扑无关三维图像。第二种新方法，多对多电荷-光匹配，随后将TPC电荷活动与探测到的闪烁光信号配对，从而在MicroBooNE探测器中实现宇宙线μ子的强力排除。对闪烁光信号的稳健处理以及对重建三维图像的适当聚簇是该方法的基础。在本文中，我们描述这些技术的原理与算法及其在MicroBooNE实验中的成功应用。给出了这些技术性能的定量评估。利用这些技术，实现了中微子带电流事件95%效率的预选，并将非束流符合宇宙线μ子减少30倍，约80%的所选中微子带电流事件以至少70%完备性和80%纯度被重建。
