论文摘要
自发CP违规模型可以解决强大的CP问题，而无需异常的Peccei-Quinn对称性。在这项工作中，我们回顾了纳尔逊 - 巴尔（Nelson-Barr）的方法，量化了这些模型必须满足的无关质量尺度之间的特殊巧合，以便正确地重现标准模型夸克质量和违反CP的情况。我们研究了该需求与诱导的辐射校正与中子电偶极矩之间的兼容性，以及来自对撞机，Electroweak和风味可观察物的边界。
Models of spontaneous CP violation can solve the Strong CP problem without the need of an anomalous Peccei-Quinn symmetry. In this work we review the Nelson-Barr approach, quantifying a peculiar coincidence between unrelated mass scales that these models must satisfy in order to correctly reproduce the Standard Model quark masses and CP violation. We investigate the compatibility between this requirement and the induced radiative corrections to the neutron electric dipole moment, and with bounds coming from collider, electroweak and flavor observables.
