标准模型中微子有效场论（SMNEFT）是一种有效的理论，它只从标准模型规范不变算符和右手中微子场构造而成。对于六维SMNEFT算符，我们给出了Wilson系数在新物理标度和电弱标度之间的重整化群演化（RGE）的单圈反常维数矩阵的规范耦合项.我们发现，SMNEFT算子可以分为五个子集下RGE封闭。我们的结果适用于狄拉克和马约拉纳中微子。我们还讨论了算子混合模式的数值和评论一些有趣的唯象意义。
Standard Model Neutrino Effective Field Theory (SMNEFT) is an effective theory with Standard Model (SM) gauge-invariant operators constructed only from SM and right-handed neutrino fields. For the full set of dimension-six SMNEFT operators, we present the gauge coupling terms of the one-loop anomalous dimension matrix for renormalization group evolution (RGE) of the Wilson coefficients between a new physics scale and the electroweak scale. We find that the SMNEFT operators can be divided into five subsets which are closed under RGE. Our results apply for both Dirac and Majorana neutrinos. We also discuss the operator mixing pattern numerically and comment on some interesting phenomenological implications.
