Abstract

When building dark matter (DM) models, one often imposes conserved discrete symmetries to stabilize DM candidates. The simplest choice is Z2 but models with larger stabilizing groups have also been explored. Can a conserved non-Abelian group lead to a viable DM model? Here, we address this question within the three-Higgs-doublet model based on the group Σ(36), in which DM stabilization by a non-Abelian group is not only possible but inevitable. We show that the tight connections between the Higgs, fermion, and DM sectors repeatedly drive the model into conflict with the LHC results and DM observations, with the most recent LZ results playing a decisive role. We believe that the lessons learned from this study help chart the limits of what can be achieved within multi-Higgs-doublet DM models with large symmetry groups.

非阿贝尔群稳定的暗物质：来自Σ（36） 3HDM的教训

当建立暗物质（DM）模型时，人们经常施加保守的离散对称性来稳定DM候选者。最简单的选择是Z2，但也探索了具有较大稳定群的模型。一个保守的非阿贝尔群能产生一个可行的DM模型吗？在这里，我们在基于群Σ（36）的三希格斯双重态模型中解决了这个问题，其中非阿贝尔群的DM稳定不仅是可能的，而且是不可避免的。研究表明，希格斯粒子、费米子粒子和暗物质扇区之间的紧密联系反复导致模型与大型强子对撞机的结果和暗物质观测结果发生冲突，而最近的LZ结果起着决定性的作用。我们相信，从这项研究中吸取的教训有助于绘制出具有大对称群的多重希格斯-双重态DM模型所能达到的极限。2025年由美国物理学会出版
