模定域化和弦定域场理论彻底改变了量子场论的几个关键方面。它们加强了局部对称性直接来自量子理论的论点,但整体规范不变性通常仍然是一个没有根据的假设,需要逐案检验。有了这些现代工具,我们在这里重新考虑经典的Okubo-Marshak论点的不存在的“强CP问题”的量子色动力学。
Modular localization and the theory of string-localized fields have revolutionized several key aspects of quantum field theory. They reinforce the contention that local symmetry emerges directly from quantum theory, but global gauge invariance remains in general an unwarranted assumption to be examined case by case. Armed with those modern tools, we reconsider here the classical Okubo–Marshak argument on the non-existence of a “strong CP problem” in quantum chromodynamics.
