论文摘要
在精确的A4对称性下，对三个Higgs Doublet模型（3HDM）对称引起了极大的兴趣。我们提供了完整的分析性和充分条件，使某个模型中的中性方向是全球最小值，讨论了许多涉及的微妙之处。我们还提供了许多数值示例，以突出这些问题。然后，我们转向破坏电荷的方向，为从下方（BFB）电位界定的安全分析足够条件。基于广泛的数值模拟，我们沿电荷断裂方向讨论了BFB上的一个猜想。
There has been a great interest in three Higgs doublet models (3HDM) symmetric under an exact A4 symmetry. We provide the complete analytic necessary and sufficient conditions for a point to be the global minimum along the neutral directions in such models, discussing many of the subtleties involved. We also present a number of numerical examples, to highlight those issues. We then turn to the directions which break electric charge, presenting a safe analytical sufficient condition for bounded from below (BFB) potentials. Based on extensive numerical simulations, we discuss one conjecture on BFB along charge breaking directions.
