摘要
对于在地球表面或附近运行以探测中微子相互作用的大型液氩时间投影室（LArTPC）而言，由于巨大的宇宙线通量和 TPC 的长漂移时间，宇宙成因本底的排除是一项关键且具挑战性的任务。我们介绍了一种基于线单元（Wire-Cell）三维（3D）事件重建的、用于 LArTPC 的优越宇宙线本底排除流程。从初始 1:20,000 的中微子与宇宙线本底之比出发，我们在 MicroBooNE 实验的数据上展示了这些工具，并创建了一个高性能的通用中微子事件选择，在可见能量区域大于 O(200)~MeV 时宇宙线污染为 14.9\%（9.7\%）。对于包含性 带电电流和 带电电流相互作用，中微子相互作用选择效率分别为 80.4\% 和 87.6\%。与现有重建算法相比，这一显著改进标志着朝向实现在地球表面附近运行的 LArTPC 中微子振荡实验科学目标的一个重大里程碑。
