论文摘要
$ \ Mathbb Z_2 \ times \ Mathbb Z_2 $ -SMMETRIC 3HDM潜力，有时称为Weinberg的3HDM潜力，可以适应显式和自发的CP侵犯和自然风味的侵犯以及自然风味，并且因此与CP违规有关的CP违规与现实的扩展Higgs部门有关。该模型具有一个有趣的制度，由单个参数控制，在该参数中，它获得了近似的全局$ u（1）\ times u（1）$对称性，导致CP违反CP违反效果很小，并且两个伪基石玻色子存在于标量谱系中。从参数空间扫描中，我们发现，在具有类似Smlike Higgs玻色子的现实实现中，该模型主要导致存在光额外的Higgs玻色子，其质量低于Smike Higgs Boson。
The $\mathbb Z_2\times \mathbb Z_2$-symmetric 3HDM potential, sometimes called Weinberg's 3HDM potential, can accommodate both explicit and spontaneous CP violation as well as natural flavour conservation and is hence relevant for studies of CP violation coming from a realistic extended Higgs sector. The model has an interesting regime, controlled by a single parameter, where it acquires an approximate global $U(1) \times U(1)$ symmetry which causes CP violating effects to be small and two pseudo-Goldstone bosons to be present in the scalar spectrum. From parameter space scans, we find that, in a realistic implementation featuring an SM-like Higgs boson, this model predominantely leads to the existence of light additional Higgs bosons with a mass lower than the SM-like Higgs boson.
