摘要
位于费米实验室的MicroBooNE液氩时间投影室是一项中微子实验，致力于短基线振荡研究、液氩中中微子截面测量，以及这一新型探测器技术的研究与开发。准确而精密的量能学测量对于事件重建至关重要，其通过利用TPC以毫米分辨率沿粒子径迹测量单位长度的沉积能量来实现。我们描述了探测器中非均匀的量能学重建性能，显示出对粒子径迹角度的依赖性。这种非均匀的重建直接影响从量能学测量推断粒子类型的粒子鉴别算法的性能。本工作提出了一种考虑并有效解决这种非均匀性的新粒子鉴别方法。新开发的方法与先前的算法相比表现出改进的性能，在束流数据上执行较为宽松的径迹选择时，质子选择效率为94%，缪子误识别率为10%。通过识别相互作用中的排他末态进一步展示了该性能。虽然使用MicroBooNE数据和模拟开发，该方法易于应用于未来的LArTPC实验，如SBND、ICARUS和DUNE。
