AI 中文摘要
在本研究中，我们在中微子-核电荷流准弹性相互作用的背景下探索超标度变量 $\psi'$。基于中微子导向的超标度变量 $\psi'$ 的定义，我们将其重新参数化为中微子能量重建偏差的函数，从而在超标度形式主义与中微子能量重建之间建立直接的概念性和分析性联系。该方法允许重建的 $\psi'$ 的强子部分在准弹性点附近展开，产生仅依赖于出射缪子运动学的新观测量。同时，所得分布仍对底层核动力学敏感，并随核模型的不同而变化。其中，一个新识别的量 $L_1$，仅由出射缪子运动学构建，为中微子能量重建偏差提供了核物理约束。该观测量在很大程度上继承了 $\psi'$ 在不同中微子通量和核靶标下的标度性质。使用类似ND280的 $\nu_\mu$ 和 $\bar{\nu}_\mu$ 碳靶蒙特卡洛样本研究核模型依赖性，这些样本由NEUT、NuWro和GENIE中实现的几种核模型生成，而跨实验条件的稳定性则通过额外的碳基和氩基通量-靶标配置进行测试。
英文摘要
In this study, we explore the superscaling variable $ψ'$ within the context of neutrino-nucleus charged-current quasielastic interactions. Building on the neutrino-oriented definition of the superscaling variable $ψ'$, we reparametrize it in terms of the neutrino-energy reconstruction bias, thereby establishing a direct conceptual and analytical connection between the superscaling formalism and neutrino-energy reconstruction. This approach allows the hadronic part of the reconstructed $ψ'$ to be expanded around the quasielastic point, yielding new observables that depend only on the outgoing-muon kinematics. At the same time, the resulting distributions remain sensitive to the underlying nuclear dynamics and vary across nuclear models. Among them, a newly identified quantity $L_1$, constructed solely from the outgoing-muon kinematics, provides a nuclear-physics constraint on the neutrino-energy reconstruction bias. This observable largely inherits the scaling properties of $ψ'$ across different neutrino fluxes and nuclear targets. The nuclear-model dependence is investigated using ND280-like $ν_μ$ and $\barν_μ$ Monte Carlo samples on carbon, generated with several nuclear models implemented in NEUT, NuWro, and GENIE, while the stability across experimental conditions is tested using additional carbon- and argon-based flux-target configurations.
