论文摘要
本文总结了$ν_μ$和$ \barν_μ$ CC0 $π$ cc0 $π$横截面测量的艺术状态，并讨论了Genie V3中相关的核模型，参数化和不确定性。 CC0 $π$事件拓扑在几个GEV能量范围的实验中很常见。尽管它的主要贡献来自准弹性相互作用，但这种拓扑仍然尚未得到很好的理解。利用Genie Global Analysis框架来分析MiniBoone，T2K和Minerva的CC0 $π$数据集。进行每个实验的部分调子，为讨论数据集之间的紧张关系提供了共同的基础。结果提供了对核CC0 $π$数据集的改进描述，以及每个实验的数据驱动的不确定性。这项工作是迈向Genie Global曲调的一步，可以提高我们对中微子相互作用对核的理解。它遵循早期的精灵工作，对氢和氘的中微子散射数据集进行分析。
This article summarizes the state of the art of $ν_μ$ and $\barν_μ$ CC0$π$ cross-section measurements on carbon and argon and discusses the relevant nuclear models, parametrizations and uncertainties in GENIE v3. The CC0$π$ event topology is common in experiments at a few-GeV energy range. Although its main contribution comes from quasi-elastic interactions, this topology is still not well understood. The GENIE global analysis framework is exploited to analyze CC0$π$ datasets from MiniBooNE, T2K and MINERvA. A partial tune for each experiment is performed, providing a common base for the discussion of tensions between datasets. The results offer an improved description of nuclear CC0$π$ datasets as well as data-driven uncertainties for each experiment. This work is a step towards a GENIE global tune that improves our understanding of neutrino interactions on nuclei. It follows from earlier GENIE work on the analysis of neutrino scattering datasets on hydrogen and deuterium.
