论文摘要
标准模型中微子有效场理论（SMNEFT）是一种有效的理论，具有仅由SM和右中微子场构建的标准模型（SM）仪表不变的操作员。对于整个尺寸六个SMNEFT运算符，我们介绍了新物理量表和电动量表之间的Wilson系数的重新归一化组演化（RGE）的一环异常尺寸矩阵的量规耦合项。我们发现，SMNEFT操作员可以分为五个在RGE下关闭的子集。我们的结果同时适用于狄拉克和主要中微子。我们还通过数值讨论操作员混合，并评论一些有趣的现象学含义。
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.
