利用希尔伯特级数技术，我们介绍了一种根据标准模型有效场论(SMEFT)算符的CP性质对其进行分类的系统方法。我们的方法使得在几秒钟内列举违反CP对称性的算子成为可能。在CP变换下，给出了8维算子的完全分类，列出了14维的奇数或违反CP算子的个数，并给出了一个允许任何人复制我们结果的形式的伴码。
We introduce a systematic method to classify the Standard Model Effective Field Theory (SMEFT) operators based on their CP properties with the Hilbert series techniques. Our method makes it possible to enumerate operators violating CP symmetry in a few seconds. We present the complete classification of dimension eight operators under CP transformation, and the number of CP-odd or CP-violating operators are listed up to dimension 14. We also provide a companion code in Form that allows anybody to reproduce our results.
