标题： P and T Violation From Certain Dimension Eight Weinberg Operators

摘要： 魏因伯格类型的八维算符已被证明对CP破坏现象（例如中子的电偶极矩）有重要的贡献。 在这篇短文中，我们展示了与这些算符相关联的（并且预期会同样发生）的算符如何引起时间反演破坏的现象，例如原子电偶极矩。 我们还估计了诱导的宇称破坏现象，例如原子态中微小的“错误”宇称混杂，并发现它们可以忽略不计。 使用harvmac.tex和epsf.tex；提交了一幅图作为uu编码、压缩的EPS文件。 显示英文摘要

摘要： Dimension eight operators of the Weinberg type have been shown to give important contributions to CP violating phenomena, such as the electric dipole moment of the neutron. In this note we show how operators related to these (and expected to occur on equal footing) can give rise to time-reversal violating phenomena such as atomic electric dipole moments. We also estimate the induced parity violating phenomena such as small ``wrong'' parity admixtures in atomic states and find that they are negligible.
