论文摘要
事实证明，建立Lepton-number-violating有效运营商的紫外线完成是研究和分类主要中微子质量模型的一种有用方法。在本文中，我们描述并实施了一种系统化此模型构建过程的算法。我们使用算法来生成操作员的所有树级完整的计算表示，直到质量含量11。几乎所有这些都对应于辐射性中微子质量的模型。我们的工作包括涉及衍生产品的运营商，与每个操作员相关的新物理量表上界限的更新估计，对模型的各种特征的分析以及一些示例。我们发现，许多运营商不承认任何完成都不会为中微子质量产生较低维度的操作员或更大的贡献，因此将他们排除在中微子质量的一代中起着主导作用。此外，我们表明，最多有五个模型，其中包含三个或更少的外来多重组，可以预测必须低于100 TEV的新物理学。伴随这项工作，我们还提供了一个可搜索的数据库，其中包含我们的所有结果以及用于查找完成的代码。我们强调的是，我们的方法范围不仅仅是对中微子质量模型的研究，并且可能有助于在其他有效的领域理论中生成高维操作员的完成。
Building UV completions of lepton-number-violating effective operators has proved to be a useful way of studying and classifying models of Majorana neutrino mass. In this paper we describe and implement an algorithm that systematises this model-building procedure. We use the algorithm to generate computational representations of all of the tree-level completions of the operators up to and including mass-dimension 11. Almost all of these correspond to models of radiative neutrino mass. Our work includes operators involving derivatives, updated estimates for the bounds on the new-physics scale associated with each operator, an analysis of various features of the models, and a look at some examples. We find that a number of operators do not admit any completions not also generating lower-dimensional operators or larger contributions to the neutrino mass, ruling them out as playing a dominant role in the neutrino-mass generation. Additionally, we show that there are at most five models containing three or fewer exotic multiplets that predict new physics that must lie below 100 TeV. Accompanying this work we also make available a searchable database containing all of our results and the code used to find the completions. We emphasise that our methods extend beyond the study of neutrino-mass models, and may be useful for generating completions of high-dimensional operators in other effective field theories.
