The modeling of neutrino-nucleus interactions constitutes a challenging source of systematic uncertainty for the extraction of precise values of neutrino oscillation parameters in long-baseline accelerator neutrino experiments. To improve such modeling and minimize the corresponding uncertainties, a new generation of detectors is being developed, which aim to measure the complete final state of particles resulting from neutrino interactions. In order to fully benefit from the improved detector capabilities, precise simulations of the nuclear effects on the final-state nucleons are needed. This article presents the study of the in-medium propagation of knocked-out protons, i.e., final-state interactions (FSI), comparing the NuWro and INCL cascade models. The INCL model is used here for the first time to predict exclusive final states in measured neutrino interaction cross sections. This study of INCL in the framework of neutrino interactions features various novelties, including the production of nuclear clusters (e.g., deuterons, $\alpha$ particles) in the final state. The paper includes a complete characterization of the final state after FSI, comparisons to available measurements of single transverse variables, and an assessment of the observability of nuclear clusters.

用 INCL 和 NuWro 级联模型研究中微子核散射中质子的终态相互作用

中微子-核相互作用的建模构成了系统不确定性的一个具有挑战性的来源，用于在长基线加速器中微子实验中提取中微子振荡参数的精确值。为了改进这种建模并最大限度地减少相应的不确定性，正在开发新一代探测器，旨在测量由中微子相互作用产生的粒子的完整最终状态。为了充分受益于改进的探测器能力，需要精确模拟核效应对终态核子的影响。本文介绍了敲除质子在介质中传播的研究，即终态相互作用 (FSI)，比较了 NuWro 和 INCL 级联模型。这里首次使用 INCL 模型来预测测量的中微子相互作用截面中的唯一最终状态。这项在中微子相互作用框架下对 INCL 的研究具有各种新颖性，包括核簇（例如，氘核、$\alpha$粒子）处于最终状态。该论文包括对 FSI 后最终状态的完整表征，与单个横向变量的可用测量值的比较，以及对核团簇可观测性的评估。
