论文摘要
我们研究了具有柔和破碎的对称性的多基格斯模型的最小化。几何最小化的强大方法可以使具有较大对称性的多基格斯模型的分析最小化。当这些对称性柔和破碎时，需要对该方法进行调整。我们提出了一个有用的概括，该概括通过将程序应用于受限的轨道空间来考虑软术术语对电势的二次部分的影响。我们通过查找和分类为$ s_4 $ $ s_4 $多吉格斯模型的最小值来体现我们的新方法，该模型柔和地破碎了。
We study the minimization of multi-Higgs models with symmetries that are softly-broken. The powerful method of geometric minimization enables analytic minimization of multi-Higgs models with large symmetries. When these symmetries are softly-broken, the method needs to be adapted. We propose a useful generalization that considers the effect of the soft-breaking terms to the quadratic part of the potential, by applying the procedure to restricted orbit spaces. We exemplify our novel methodology by finding and classifying the minima for an $S_4$ multi-Higgs model that is softly-broken with specific terms.
