论文摘要
我们考虑使用惰性Higgs Doublet的标准模型（SM）扩展，该二键也包含两三组$ su（2）_l $ $ treeplet fermions，具有超重零，并分析了对场景的electroweak真空的稳定性。该模型代表了具有暗物质候选者中微子质量产生的III型逆Seesaw机制。在决定Electroweak真空的命运时，已经实现了具有两环β功能的有效潜在方法计算。与标准模型相比，弱量规耦合$ g_2 $显示出不同的行为。 $ G_2 $的修改后运行以及希格斯四分之一的耦合和III型Yukawa耦合对于确定Electroweak真空的稳定性至关重要。两到三代这样的三胞胎费米子之间的相互作用表明，如果我们渴望获得普朗克尺度稳定性，则有利于两代人的扩展。 Higgs四分之一耦合，III型Yukawa的边界和三胞胎费米昂世代的数量是针对不同类型的III Fermions的不同质量规模的。评论了LHC和其他实验的惰性双线和III型费米的现象学。
We consider the extension of the Standard Model (SM) with an inert Higgs doublet that also contains two or three sets of $SU(2)_L$ triplet fermions with hypercharge zero and analyze the stability of electroweak vacuum for the scenarios. The model represents a Type-III inverse seesaw mechanism for neutrino mass generation with a Dark matter candidate.An effective potential approach calculation with two-loop beta function have been carried out in deciding the fate of the electroweak vacuum. Weak gauge coupling $g_2$ shows a different behaviour as compared to the Standard Model. The modified running of $g_2$, along with the Higgs quartic coupling and Type-III Yukawa couplings become crucial in determining the stability of electroweak vacuum. The interplay between two and three generations of such triplet fermions reveals that extensions with two generations is favoured if we aspire for Planck scale stability. Bounds on the Higgs quartic couplings, Type-III Yukawa and number of triplet fermion generations are drawn for different mass scale of Type-III fermions. The phenomenologies of inert doublet and Type-III fermions at the LHC and other experiments are commented upon.
