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.
Storage rings as detectors for relic gravitational-wave background ?
我们认为储存环可以用于低频引力波背景的探测。我们解释了由Takao和Shimada观察到的SPring-8储存环的机器周长的系统收缩(Proceedings of EPAC 2000,Vienna,2000,p.1572),这是由遗迹引力波背景的影响引起的。我们表明,系统的收缩的机器周长可以解释的遗迹引力波的背景,即使它被视为一个随机系统传入的平面上的机器周长从宇宙的各个方面。我们表明,机器周长的系统收缩率不取决于存储环的半径,并且对于任何半径的存储环都应该是通用的。

本文重新考虑了GSI储存环实验中类氢母离子P电子俘获衰变中的中微子信号,着重讨论了P -> D + e-neutrino两体衰变中子离子D在储存环中的准圆运动。有人认为,在某种程度上,子离子被检测到,这些检测率可能会表现出调制的周期为秒级,类似于GSI存储环实验中报道的两体衰变率[1,2]。在储存环中或使用陷阱的新的专门实验可以探索这些调制。
