论文摘要
在展开，通量平均中微子横截面测量中处理通量不确定性的确切方法可能会导致细微的问题，而将结果与模型预测进行比较。报告（未知）真实通量中的横截面与报告从（未知）真实通量推断为固定参考通量的横截面之间是有区别的。前者进行了许多（大多数？）当前的分析，而结果则与模型预测进行了比较，就好像它们是后者一样。这导致（一部分）通量形状的不确定性被忽略，可能导致错误的物理结论。效果的大小估计是亚优势的，但在T2K和Minerva的两个示例测量中不可忽略。本文描述了问题是如何出现的，并提供了指令，以了解如何正确治疗磁通形状的不确定性。
The exact way of treating flux shape uncertainties in unfolded, flux-averaged neutrino cross-section measurements can lead to subtle issues when comparing the results to model predictions. There is a difference between reporting a cross section in the (unknown) real flux, and reporting a cross section that was extrapolated from the (unknown) real flux to a fixed reference flux. A lot of (most?) current analyses do the former, while the results are compared to model predictions as if they were the latter. This leads to (part of) the flux shape uncertainty being ignored, potentially leading to wrong physics conclusions. The size of the effect is estimated to be sub-dominant, but non-negligible in two example measurements from T2K and MINERvA. This paper describes how the issue arises and provides instructions for possible ways how to treat the flux shape uncertainties correctly.
