本文系统研究了大气中微子电荷电流相互作用在大型液态闪烁体探测器中的事件特征和中微子-反中微子鉴别物理。研究包括初级中微子相互作用、最终态粒子的连续二次相互作用以及最终中子捕获。我们仔细研究了最终态带电轻子和强子的性质，为中微子和反中微子相互作用提供了不同的不弹性度和捕获中子数分布。这些分布被用于评估中微子-反中微子鉴别的定量性能。我们的发现为大型液态闪烁体探测器中的大气中微子振荡研究奠定了基础，特别是为确定中微子质量顺序提供基础。
英文摘要
In this work, we present a systematic study of the event characteristics and physics of neutrino-antineutrino discrimination associated with atmospheric neutrino charged-current interactions in large liquid scintillator detectors. This study encompasses the primary neutrino interactions, the sequential second interactions of final-state particles, and the final neutron captures. We carefully investigate the properties of final-state charged leptons and hadrons, providing distinct distributions of inelasticity and captured neutron multiplicity for both neutrino and antineutrino interactions. These distributions are employed to assess the quantitative performance of neutrino-antineutrino discrimination. Our findings lay the groundwork for atmospheric neutrino oscillation studies in large liquid scintillator detectors, particularly in the determination of neutrino mass ordering.
