论文摘要
两-higgs-triplet模型（2HTM）为我们提供了一种同时考虑微小中微子质量和观察到的物质 - 抗逆不是对称性的有吸引力的方法。在本演讲中，我们使用双线性场形式主义研究了2HTM中标量潜力的意外对称性。基于组理论参数，我们证明最大对称组为$ {\ rm so（4）} $。我们仔细分析了$ {\ rm so（4）} $的所有子组，并发现2HTM的标量潜力中有八种不同类型的意外对称性。
The two-Higgs-triplet model (2HTM) provides us with an attractive way to simultaneously account for tiny neutrino masses and the observed matter-antimatter asymmetry in our Universe. In this talk, we study the accidental symmetries of the scalar potential in the 2HTM using the bilinear-field formalism. Based on the group-theoretical arguments, we prove that the maximal symmetry group is ${\rm SO(4)}$. We carefully analyze all the subgroups of ${\rm SO(4)}$, and find that there are eight distinct kinds of accidental symmetries in the scalar potential of the 2HTM.
