论文摘要
我们解决了标准模型（SM）的臭名昭著的稳定性，并将其提升为模型构建任务：在不遇到Subplanckian Landau Poles的情况下，将SM稳定到Planck量表所需的新成分是什么？使用矢量样费米（VLFS）的SM扩展，我们绘制了HIGGS稳定性的相应景观。我们发现，由新的SM电荷载体触发的量规门户机构以微创的方式为稳定性带来了巨大的空间。我们还找到了具有Higgs关键性的模型，而Yukawa门户网站以更强的耦合开放。几种模型允许在TEV范围内使用VLF，可以在LHC上搜索。对于非平凡的风味结构，会出现严重的风味中性电流限制，从而补充了稳定性的那些，并将下部费米昂质量推至$ \ nathcal {o}（10^3 \，\ text {tev}）$。
We address the notorious metastability of the standard model (SM) and promote it to a model building task: What are the new ingredients required to stabilize the SM up to the Planck scale without encountering subplanckian Landau poles? Using the SM extended by vector-like fermions (VLFs), we chart out the corresponding landscape of Higgs stability. We find that the gauge portal mechanism, triggered by new SM charge carriers, opens up sizeable room for stability in a minimally invasive manner. We also find models with Higgs criticality, and Yukawa portals opening up at stronger coupling. Several models allow for VLFs in the TeV-range, which can be searched for at the LHC. For nontrivial flavor structure severe flavor-changing neutral current constraints arise which complement those from stability, and push lower fermion masses up to $\mathcal{O}(10^3\,\text{TeV})$.
