摘要
宇宙线（CR）相互作用对于地面探测器中的中微子振荡与截面测量而言，可能是一种具有挑战性的背景来源。我们提出了在利用液氩时间投影室（LArTPCs）测量的、末态含一个μ子和一个质子的带电流类准弹性（CCQE-like）中微子相互作用测量中排除CR的方法。利用MicroBooNE探测器采集的宇宙线数据样本，并与模拟的中微子散射事件相混合，我们建立了一套事件筛选准则，由此产生的事件样本具有极小的CR背景贡献。根据所用筛选准则的不同，可实现50%至80%的纯度，信号选择效率为50%至25%，且纯度越高效率越低。尽管使用了MicroBooNE探测器的特定数据集以及针对CCQE-like事件优化的筛选准则数值，此处提出的概念具有通用性，可适用于LArTPCs中各类排他性νμ相互作用的研究。
