论文摘要
我们通过在TEV量表上添加新的矢量样费米来最少扩展标准模型字段内容，以允许以现实的量表量表耦合统一。我们将模型嵌入了$ SU（5）$ Grand Unified理论中，该理论在渐近安全，并具有相互作用的固定点的量学耦合。 $ U（1）$ gauge和Higgs耦合没有Landau电线杆。量规，Yukawa和Higgs耦合从固定点追溯，并以大统一量表匹配到缩放到相同能量的标准模型的量表。所有耦合，其固定点值和关键指数始终保留在扰动状态中。
We minimally extend the Standard Model field content by adding new vector-like fermions at the TeV scale to allow gauge coupling unification at a realistic scale. We embed the model into a $SU(5)$ grand unified theory that is asymptotically safe and features an interacting fixed point for the gauge coupling. There are no Landau poles of the $U(1)$ gauge and Higgs couplings. Gauge, Yukawa and Higgs couplings are retraced from the fixed point and matched at the grand unification scale to those of the Standard Model rescaled up to the same energy. All couplings, their fixed point values and critical exponents always remain in the perturbative regime.
