QCD迹反常是量子场论中已被公认的教科书级结论，具有几个显著特征：（1）它源于紫外（UV）标度下标度对称性的量子破缺，但与所使用的特定紫外调节器无关，无论是格点正则化还是维数正则化；（2）尽管名义上与${\cal O}(α_s)$成正比，但它不存在重整化方案的歧义；（3）它没有紫外发散，因此与标度无关。遗憾的是，这些重要特征在最近提出的可约基重整化方法中遭到了否定，进而引发了人们对与反常相关的核子物理的误解，包括核子质量的起源和内部作用力的问题。
英文摘要
The QCD trace anomaly is a well-established textbook result in quantum field theory with several prominent features: (1) it arises from the quantum breaking of scale symmetry at ultraviolet (UV) scales, yet is independent of the particular UV regulator used, whether lattice or dimensional regularization; (2) although it is nominally proportional to (${\cal O}(α_s)$), it is free of renormalization-scheme ambiguity; and (3) it is free of UV divergences and is therefore scale independent. Unfortunately, these important features have been undermined in the recently introduced reducible-basis renormalization, leading to misunderstandings of anomaly-related nucleon physics, including the origins of nucleon mass and internal forces.
