We summarize the results of a study performed within the GENIE global analysis framework, revisiting the GENIE bare-nucleon cross-section tuning and, in particular, the tuning of (a) the inclusive cross section, (b) the cross section of low-multiplicity inelastic channels (single-pion and double-pion production), and (c) the relative contributions of resonance and nonresonance processes to these final states. The same analysis was performed with several different comprehensive cross-section model sets available in GENIE Generator v3. In this work we perform a careful investigation of the observed tensions between exclusive and inclusive data, and install analysis improvements to handle systematics in historic data. All tuned model configurations discussed in this paper are available through public releases of the GENIE Generator. With this paper we aim to support the consumers of these physics tunes by providing comprehensive summaries of our alternate model constructions, of the relevant datasets and their systematics, and of our tuning procedure and results.

GENIE v3 中的中微子-核子截面模型调整
我们总结了在 GENIE 全局分析框架内进行的一项研究的结果，重新审视了 GENIE 裸核横截面调谐，特别是（a）包容性横截面，（b）低-多重非弹性通道（单π介子和双π介子产生），以及（c）共振和非共振过程对这些最终状态的相对贡献。使用 GENIE Generator v3 中可用的几个不同的综合横截面模型集进行了相同的分析。在这项工作中，我们对观察到的排他性和包容性数据之间的紧张关系进行了仔细调查，并安装了分析改进来处理历史数据中的系统性问题。本文中讨论的所有优化模型配置均可通过 GENIE Generator 的公开版本获得。
