论文摘要
我们研究了$ a_4 $或$ s_4 $对称的三重速度模型,该模型柔和破碎。专注于轻轻打破各个对称性但保留三胞胎真空期望值的方向,我们分析了物理状态的质量并讨论它们的衰变。与先前研究的对称性相反,我们发现某些具有稳定状态的病例,这些案例受到软性参数和真空的残留对称性保护的稳定状态。
We study multi-Higgs models with a triplet of $A_4$ or $S_4$ symmetry that is softly-broken. Focusing on parameters that softly break the respective symmetries but preserve the directions of the vacuum expectation values of the triplet we analyse the masses of physical states and discuss their decays. In contrast with previously studied symmetries, we find some cases with stable states that are protected by residual symmetries left unbroken by both the soft-breaking parameters and by the vacuum.
