摘要:

我们表明,质子储存环实验设计,以寻找质子电偶极矩也可以用来寻找近直流自旋进动引起的暗能量和超轻暗物质。这些实验对类轴子场和矢量场都很敏感。目前的技术允许探测这些现象,其数量级超过天体物理极限三个数量级。这些环中质子的相对论性增强使该方案具有与原子共磁力计实验相当的灵敏度,这些实验也可以探测类似的现象。这些互补的方法可用于提取信号的微观物理,使我们能够区分赝标量,磁和电偶极矩相互作用。

英文摘要:

We show that proton storage ring experiments designed to search for proton electric dipole moments can also be used to look for the nearly dc spin precession induced by dark energy and ultra-light dark matter. These experiments are sensitive to both axion-like and vector fields. Current technology permits probes of these phenomena up to three orders of magnitude beyond astrophysical limits. The relativistic boost of the protons in these rings allows this scheme to have sensitivities comparable to atomic co-magnetometer experiments that can also probe similar phenomena. These complementary approaches can be used to extract the micro-physics of a signal, allowing us to distinguish between pseudo-scalar, magnetic and electric dipole moment interactions.
