论文摘要
Francium原子被认为是搜索t，p-violating电子偶极矩的前瞻性候选系统[T. Aoki等人量子科学。技术。 6，044008（2021）]。我们证明可以将相同的实验用于轴突状颗粒（ALP）搜索。为此，我们计算了广泛的ALP质量的ALP介导相互作用的电子结构常数。使用最近对ALP电子和ALP-Nucleon耦合常数的约束，我们表明，与这些约束相对应的考虑相互作用的贡献可以为原子电偶极矩做出重大贡献。因此，可以在Francium Atom电偶极矩实验中获得更强的ALP特性限制。
The francium atom is considered as a prospective candidate system to search for the T,P-violating electron electric dipole moment [T. Aoki et al Quantum Sci. Technol. 6, 044008 (2021)]. We demonstrate that the same experiment can be used for axionlike particles (ALP) search. For this, we calculate electronic structure constants of ALP-mediated interaction for a wide range of ALP masses. Using the recently updated constraints on the ALP-electron and ALP-nucleon coupling constants, we show that the contribution of considered interactions corresponding to these constraints can give significant contribution to atomic electric dipole moment. Therefore, obtainment of stronger restrictions for ALP characteristics in the francium atom electric dipole moment experiment is possible.
