Potential advantages of chiral molecules for a sensitive search for parity violating cosmic fields are highlighted. Such fields are invoked in different models for cold dark matter or in the Lorentz-invariance violating standard model extensions and thus are signatures of physics beyond the standard model. The sensitivity of a 20-year-old experiment with the molecule CHBrClF to pseudovector cosmic fields as characterized by the parameter $|b_0^e|$ is estimated to be $\mathcal{O}({10}^{-12}\mathrm{GeV})$ employing ab initio calculations. This allows us to project the sensitivity of future experiments with favorable choices of chiral heavy-elemental molecular probes to be $\mathcal{O}({10}^{-17}\mathrm{GeV})$, which will be an improvement of the present best limits by at least two orders of magnitude.

手性分子作为直接检测P奇数宇宙场的灵敏探针

强调了手性分子对于宇宙空间奇偶校验的灵敏搜索的潜在优势。在冷暗物质的不同模型中或在违反标准模型扩展的洛伦兹不变性中调用此类字段，因此是超出标准模型的物理学的标志。用参数CHBrClF进行的已有20年历史的实验对伪矢量宇宙场的敏感性$|b_0^{Ë}|$ 估计是 $\mathcal{Ø}（{10}^{-12}\mathrm{GeV}）$采用从头计算。这使我们能够通过选择手性重元素分子探针来预测未来实验的敏感性$\mathcal{Ø}（{10}^{-17}\mathrm{GeV}）$，这将使当前的最佳限制至少提高两个数量级。
