手性分子作为灵敏探针直接探测$\mathcal{P}$ -奇宇宙场

Chiral molecules as sensitive probes for direct detection of $\mathcal{P}$-odd cosmic fields

Konstantin Gaul, Mikhail G. Kozlov, Timur A. Isaev, Robert Berger

摘要:

手性分子的赝标量和赝矢量宇宙场的类时分量的时间依赖性的直接检测的特殊优势突出。这些场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被调用,因此是超越标准模型的物理学特征。用分子CHBrClF对赝矢量宇宙场的20年实验的灵敏度,如由参数$|b^\mathrm{e}_0|$表征的,估计为$\mathcal{O}(10^{-12}\,\mathrm{GeV})$,并且允许预测用有利选择的手性分子探针的未来实验的灵敏度为$\mathcal{O}(10^{-17}\,\mathrm{GeV})$,这将是目前最佳极限的至少两个数量级的改进。

英文摘要:

Particular advantages of chiral molecules for direct detection of the time-dependence of pseudoscalar and the timelike-component of pseudovector 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 twenty year old experiment with the molecule CHBrClF to pseudovector cosmic fields as characterized by the parameter $|b^\mathrm{e}_0|$ is estimated to be $\mathcal{O}(10^{-12}\,\mathrm{GeV})$ and allows to predict the sensitivity of future experiments with favorable choices of chiral 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.
