论文摘要
具有三个HIGGS双重运动(3HDM)的模型是最近活动的来源,因为它们是标准模型问题的许多解决方案的关键组成部分;从额外的CP违规来源到暗物质候选人。我们明确计算由两到两个散射幅度的扰动单位性引起的所有对称约束3HDM的理论界限。此外,我们提出了一种基于主要未成年人的方法,该方法在所有模型(不仅是3HDM)中都易于处理大型散射矩阵。
Models with three Higgs doublets (3HDM) are the source of much recent activity, for they are key components of many solutions to the problems of the Standard Model; from extra sources of CP violation to Dark Matter candidates. We compute explicitly the theoretical bounds for all symmetry-constrained 3HDM arising from the perturbative unitarity of two-to-two scattering amplitudes. In addition, we propose a method based on principal minors that foregoes diagonalization and which is preferable in all models (not only 3HDM) dealing with large scattering matrices.
