论文摘要
中微子核相互作用的建模构成了在长基线加速器中微子实验中提取中微子振荡参数精确值的系统不确定性的挑战。为了改善这种建模并最大程度地减少相应的不确定性,正在开发新一代的探测器,旨在衡量中微子相互作用引起的颗粒的完整颗粒状态。为了完全受益于提高的检测器能力,需要精确模拟核对最终核子的影响。本文介绍了对被敲除质子(即最终状态相互作用(FSI))的中等内部传播的研究,并比较了NUWRO和含有级联模型。在这里首次使用包含模型来预测中微子相互作用的独家最终状态。这项包含中微子相互作用框架的研究具有各种新颖性,包括在最终状态下的核簇(例如杜特龙,$α$颗粒)的产生。本文包括FSI后最终状态的完整表征,与单个横向变量的可用测量值进行比较以及评估核簇的可观察性。
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 of neutrino interactions. This study of INCL in the framework of neutrino interactions features various novelties, including the production of nuclear clusters (e.g., deuterons, $α$ 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.
