论文摘要
我们表明，通过使用与量规函数梯度成比例的非物理仪表组分，非洲量规理论的拓扑电荷是非物理的。由于手性异常的扰动的一环有限性，因此可以打破becchi-rouet-stora-tyutin对称性的Gribov副本，这可能会破坏Becchi-Rouet-stora-tyutin对称性。拓扑电荷的不可观念立即导致解决强大的CP问题。我们还带来了重要的后果，例如轴向$ u（1）$对称性的物理相关性，真空能量的$θ$独立性，拓扑激体的非物理性以及实现SPHALERON诱导的Baryogenesewiss的不可能以及脊椎磁效应的可能性。非物理真空角度和轴向$ u（1）$对称性也意味着Cabibbo-Kobayashi-Maskawa矩阵的CP阶段是CP违反标准模型的唯一来源。
We show that the topological charge of nonabelian gauge theory is unphysical by using the fact that it always involves the unphysical gauge field component proportional to the gradient of the gauge function. The removal of Gribov copies, which may break the Becchi-Rouet-Stora-Tyutin symmetry, is irrelevant thanks to the perturbative one-loop finiteness of the chiral anomaly. The unobservability of the topological charge immediately leads to the resolution of the Strong CP problem. We also present important consequences such as the physical relevance of axial $U(1)$ symmetry, the $θ$-independence of vacuum energy, the unphysicalness of topological instantons, and the impossibilities of realizing the sphaleron induced baryogenesis as well as the chiral magnetic effect. The unphysical vacuum angle and the axial $U(1)$ symmetry also imply that the CP phase of the Cabibbo-Kobayashi-Maskawa matrix is the sole source of CP violation of the standard model.
