论文摘要
长基线（LBL）中微子实验利用沉重的核靶标进行中微子散射，其中核作用在测量中微子振荡参数时会引起并发症，最高精度。这些核效应尚未完全理解，因此需要量化，因为它们有助于系统的不确定性。中微子能量的精确重建是测量振荡参数的主要组成部分之一，需要以很高的精度重建中微子能量。在这项工作中，我们使用两个模型使用两个模型来研究共振（RES）相互作用的影响，用于$ν_μ\rightArrowν_μ$ $ $ n no $ν$一个实验的消失通道，对中微子核心散射横截面，事件，中微子振荡参数敏感性。我们还合并了no $ν$ a的现实检测器规范。为了量化由于RES相互作用引起的系统不确定性，我们比较了两个模型RES过程的横截面，事件和灵敏度分析-Rein-Sehgal和Berger-Sehgal，并评论哪些模型会产生更精确的精度。我们观察到RES过程有显着贡献，应在提取中微子振荡参数的同时仔细包括在模型中。
The long baseline (LBL) neutrino experiments use heavy nuclear targets for neutrino scattering in which nuclear effects give rise to complications in measuring the neutrino oscillation parameters up to high precision. These nuclear effects are not yet fully understood and therefore need to be quantified as they contribute to the systematic uncertainties. Precision reconstruction of neutrino energy is one of the main components in measuring the oscillation parameters, and it is required that the neutrino energy is reconstructed with very high precision. In this work, we investigate the effects of the resonance (RES) interaction process using two models for carbon target for $ν_μ\rightarrowν_μ$ disappearance channel of the NO$ν$A experiment, on neutrino-nucleus scattering cross section, events, and neutrino oscillation parameter sensitivity. We also incorporate the realistic detector specifications of NO$ν$A. To quantify the systematic uncertainties due to RES interactions, we compare the cross-sections, events, and sensitivity analysis for two models of RES processes - Rein-Sehgal and Berger-Sehgal, and comment on which model produces more precision. We observe that RES processes contribute significantly, and should be included carefully in models while extracting neutrino oscillation parameters.
