我们提出的国家科学基金会项目范围研讨会的结果，其目的是评估目前的状态计算的核矩阵元素管理中微子双β衰变，并确定是否需要更多的工作。在回顾了有效场论、晶格量子色动力学和从头算核结构理论应用于双β衰变的重要最新进展后，我们讨论了核物理不确定性量化的最新进展，然后构建了所有这些领域工作的路线图，以充分补充正在运行和开发中的日益敏感的实验。该路线图包括理论和计算物理学领域的具体项目，以及使用贝叶斯方法来量化模型内和模型间不确定性。这个雄心勃勃的计划的目标是在实验人员感兴趣的所有核中提供一组准确和精确的矩阵元素，并仔细评估不确定性。这样的计算将允许从无中微子双β衰变的观测或未观测中得出明确的结论，无论是什么新物理学在起作用。
We present the results of a National Science Foundation Project Scoping Workshop, the purpose of which was to assess the current status of calculations for the nuclear matrix elements governing neutrinoless double-beta decay and determine if more work on them is required. After reviewing important recent progress in the application of effective field theory, lattice quantum chromodynamics, and ab initio nuclear-structure theory to double-beta decay, we discuss the state of the art in nuclear-physics uncertainty quantification and then construct a roadmap for work in all these areas to fully complement the increasingly sensitive experiments in operation and under development. The roadmap includes specific projects in theoretical and computational physics as well as the use of Bayesian methods to quantify both intra- and inter-model uncertainties. The goal of this ambitious program is a set of accurate and precise matrix elements, in all nuclei of interest to experimentalists, delivered together with carefully assessed uncertainties. Such calculations will allow crisp conclusions from the observation or non-observation of neutrinoless double-beta decay, no matter what new physics is at play.
