论文摘要
长基线（LBL）中微子实验旨在测量中微子振荡参数高精度。这些实验使用核靶标进行中微子散射，因此具有复杂的核效应。核效应及其在中微子振荡参数的敏感性测量中的渗透尚未完全了解，因此需要仔细处理。在最近的一项工作[1]中，我们报告了使用运动中微子能量重建运动方法的实验的一些结果，在这种情况下，观察到与理想的检测器相比，在该分析中，核效应在灵敏度分析中很重要，并且包括现实的检测器设置规范在此分析中增加了不确定性。通过这种动机，在这项工作中，我们使用了两种中微子能量重建方法 - 运动和量热法，包括核效应，并研究它们对敏感性分析的影响。 We consider nuclear interactions such as RPA and 2p2h and compare two energy reconstruction methods with reference to events generation, measurement of neutrino oscillation parameters $Δm_{32}^2$ and $θ_{23}$ for disappearance channel, mass hierarchy sensitivity, and CP-violation sensitivity for appearance channel of the NO$ν$A experiment.可以观察到，与量热法相比，运动学方法具有理想的检测器设置，对核效应表现出显着依赖性。我们还研究了这两种方法（具有核效应）对NO $ν$ a的现实检测设置的影响，并发现与运动学方法相比，量热法显示了灵敏度轮廓的偏差（不确定性增加）。发现这对于质量层次结构以及中微子和抗肿瘤传入梁都是正确的。
Long baseline (LBL) neutrino experiments aim to measure the neutrino oscillation parameters to high precision. These experiments use nuclear targets for neutrino scattering and hence are inflicted with complexities of nuclear effects. Nuclear effects and their percolation into sensitivity measurement of neutrino oscillations parameters are not yet fully understood and therefore need to be dealt with carefully. In a recent work [1], we reported some results on this for NO$ν$A experiment using the kinematic method of neutrino energy reconstruction, where it was observed that the nuclear effects are important in sensitivity analysis, and inclusion of realistic detector setup specifications increases uncertainty in this analysis as compared to ideal detector case. With this motivation, in this work, we use two methods of neutrino energy reconstruction - kinematic and calorimetric, including the nuclear effects, and study their impact on sensitivity analysis. We consider nuclear interactions such as RPA and 2p2h and compare two energy reconstruction methods with reference to events generation, measurement of neutrino oscillation parameters $Δm_{32}^2$ and $θ_{23}$ for disappearance channel, mass hierarchy sensitivity, and CP-violation sensitivity for appearance channel of the NO$ν$A experiment. It is observed that with an ideal detector setup, the kinematic method shows significant dependence on nuclear effects compared to the calorimetric method. We also investigate the impact of realistic detector setup for NO$ν$A in these two methods (with nuclear effects) and find that the calorimetric method shows more bias (uncertainty increases) in sensitivity contours, as compared to the kinematic method. This is found to be true for both the mass hierarchies and for both neutrino and antineutrino incoming beams.
