四维的迹反常在逻辑上可能包含CP破坏理论中的Hirzebruch-Pontryagin密度。虽然在自由共形不动点项消失，我们实现了这样的可能性在全息重整化群，并表明它确实是可能的。迹线异常中的Hirzebruch-Pontryagin项可以作为了解共形场论中有多少CP被违反的晴雨表。
It is logically possible that the trace anomaly in four dimensions includes the Hirzebruch–Pontryagin density in CP-violating theories. Although the term vanishes at free conformal fixed points, we realize such a possibility in the holographic renormalization group and show that it is indeed possible. The Hirzebruch–Pontryagin term in the trace anomaly may serve as a barometer to understand how much CP is violated in conformal field theories.
