原子${}^{129}$中的P,T奇相互作用及其唯象应用

P,T-Odd Interactions in Atomic ${}^{129}$Xe and Phenomenological Applications

Timo Fleig, Martin Jung

摘要:

我们计算了\PT -奇标量-赝标量和张量-赝张量算符对${}^{129}$电子电偶极矩的贡献的相互作用常数,首次在前者的情况下,使用包括动态电子关联效应的相对论多体理论。这些相互作用常数是将相应的测量与标准模型之外的物理模型中的基本参数联系起来的必要成分。我们分别得到了$α_{C_S} = \left( 0.71 \pm 0.18 \right) [10^{-23}\, e~\text{cm}]$和$α_{C_T}= \left( 0.520 \pm 0.049 \right) [10^{-20}\, \left<Σ\right>_{\text{Xe}}\, e~\text{cm}]$。我们应用我们的结果来测试的两个数量之间的现象学关系,在文献中常用的,并讨论他们现在和未来的现象学影响。

英文摘要:

We calculate interaction constants for the contributions from \PT-odd scalar-pseudoscalar and tensor-pseudotensor operators to the electric dipole moment of ${}^{129}$Xe, for the first time in case of the former, using relativistic many-body theory including the effects of dynamical electron correlations. These interaction constants are necessary ingredients to relating the corresponding measurements to fundamental parameters in models of physics beyond the Standard Model. We obtain $α_{C_S} = \left( 0.71 \pm 0.18 \right) [10^{-23}\, e~\text{cm}]$ and $α_{C_T}= \left( 0.520 \pm 0.049 \right) [10^{-20}\, \left<Σ\right>_{\text{Xe}}\, e~\text{cm}]$, respectively. We apply our results to test a phenomenological relation between the two quantities, commonly used in the literature, and discuss their present and future phenomenological impact.
