我们展示了中微子扇区中的重正化群不变量。这些是通过对轻中微子的马约拉纳质量矩阵的简单分析讨论得出的。有四个不变量，它们是质量矩阵元素之间的比率。它们独立于中微子质量排序和轻子扇区混合矩阵的参数化。我们还研究了重整化群方程的两个运行参数，它可以直接显示高能尺度的中微子质量矩阵。
We show renormalization group invariants in neutrino sector. These are found from a simple analytical discussion of Majorana mass matrix for light neutrinos. There are four invariants, which are ratios among elements of the mass matrix. They are independent of neutrino mass ordering and a parameterization of mixing matrix for the lepton sector. We also investigate two running parameters of renormalization group equations, which can directly show neutrino mass matrix at the high energy scale.
