根据125GeV Higgs玻色子的观测，研究了包含I型跷跷板机制的极小Z′模型的单圈重整化群方程.该模型被作为标准模型的单态扩展的一般情况下的基准。最重要的结果是，负标量混合角相对于正值是有利的。此外，后者存在一个最小值，以及重中微子的质量的最大值，取决于真空的期望值的单线标量。
The 1-loop renormalization group equations for the minimal Z′ models encompassing a type-I seesaw mechanism are studied in the light of the 125 GeV Higgs boson observation. This model is taken as a benchmark for the general case of singlet extensions of the standard model. The most important result is that negative scalar mixing angles are favored with respect to positive values. Further, a minimum value for the latter exists, as well as a maximum value for the masses of the heavy neutrinos, depending on the vacuum expectation value of the singlet scalar.
