论文摘要
最近，已建议将YBOH分子作为寻找电子偶极矩（EEDM）的候选者，该电动偶极矩（EEDM）违反了空间奇偶校验（P）和时间逆转（T）对称性[I. Kozyryev和N. R. Hutzler，物理学。莱特牧师。 119，133002（2017）]。在本文中，我们表明，可以使用相同的系统来测量电子和核与轴突状颗粒相互作用的耦合常数。由轴突交换产生的电子核相互作用诱导t，p-侵入整个分子系统的EDM。我们表达了这种效应所产生的相应的T，p-侵入能移位，该效果在轴突质量和轴核和轴 - 电子偶联常数方面产生。
Recently the YbOH molecule has been suggested as a candidate to search for the electron electric dipole moment (eEDM) which violates spatial parity (P) and time-reversal (T) symmetries [I. Kozyryev and N. R. Hutzler, Phys. Rev. Lett. 119, 133002 (2017)]. In the present paper we show that the same system can be used to measure coupling constants of the interaction of electrons and nucleus with axionlike particles. The electron-nucleus interaction produced by the axion exchange induces T,P-violating a EDM of the whole molecular system. We express the corresponding T,P-violating energy shift produced by this effect in terms of the axion mass and product of the axion-nucleus and axion-electron coupling constants.
