论文摘要
我们研究了在当前和将来的中微子探测器上排除和发现质子衰减的统计意义。在一般环境中讨论了与多通道计数实验的频繁和修改的频繁统计量度相关的各种违反直觉缺陷，并用示例进行了说明。我们认为，基于Super-Kamiokande的数据，我们采用了这些措施来实现保守的贝叶斯动机统计措施，并采用这些措施来在各种置信度下获得当前的下部限制，从而概括了90 \％的CLEAK发布的限制。最后，我们介绍了$ p \ rightarrow \ overline c^+ $和$ p \ rightarrow e^+π^0 $ decay频道的质子部分寿命的预测和发现的预测。
We study the statistical significances for exclusion and discovery of proton decay at current and future neutrino detectors. Various counterintuitive flaws associated with frequentist and modified frequentist statistical measures of significance for multi-channel counting experiments are discussed in a general context and illustrated with examples. We argue in favor of conservative Bayesian-motivated statistical measures, and as an application we employ these measures to obtain the current lower limits on proton partial lifetime at various confidence levels, based on Super-Kamiokande's data, generalizing the 90\% CL published limits. Finally, we present projections for exclusion and discovery reaches for proton partial lifetimes in $p \rightarrow \overline νK^+$ and $p \rightarrow e^+ π^0$ decay channels at Hyper-Kamiokande, DUNE, JUNO, and THEIA.
