论文摘要
我们在正常有序中微子质量的情况下评估了对拟议的中性s中性β衰减实验的合并分析的发现概率。该发现概率在很大程度上取决于最轻的中微子质量的值，范围从质量消失的情况下为零，值范围为80-90 \％，对于当前约束的值范围低。我们研究了不同情况下的发现概率，重点是宇宙学调查测量中微子质量之和的令人兴奋的前景。当有来自不同同位素的数据可用时，核基质元件计算中的不确定性会部分补偿彼此。尽管没有批准发现，但这些搜索的理论动机和具有较高发现概率的场景的存在强烈促进了拟议的国际多相关实验计划。
We evaluate the discovery probability of a combined analysis of proposed neutrinoless double-beta decay experiments in a scenario with normal ordered neutrino masses. The discovery probability strongly depends on the value of the lightest neutrino mass, ranging from zero in case of vanishing masses and up to 80-90\% for values just below the current constraints. We study the discovery probability in different scenarios, focusing on the exciting prospect in which cosmological surveys will measure the sum of neutrino masses. Uncertainties in nuclear matrix element calculations partially compensate each other when data from different isotopes are available. Although a discovery is not granted, the theoretical motivations for these searches and the presence of scenarios with high discovery probability strongly motivates the proposed international, multi-isotope experimental program.
