论文摘要
我们研究了在存在明确的Peccei-Quinn（PQ）对称性破坏效果的情况下解决强大CP问题所需的内容。如果PQ-higgsing标量场直接耦合到标准模型部门，则指出现有的第五力实验可以对中子电偶极矩的轴质质量设置更好的约束。
We investigate what it takes for the axion to address the strong CP problem in the presence of explicit Peccei-Quinn (PQ) symmetry breaking effects besides the strong interaction. In cases where the PQ-Higgsing scalar field directly couples to the Standard Model sector, it is pointed out that existing fifth force experiments can set better constraints on the axion quality over neutron electric dipole moment.
