摘要:

轻玻色子可以介导长程力。我们表明,与背景介质,特别是宇宙中微子背景(CνB)相互作用的轻玻色子媒介子,可能诱导出依赖于介质的质量,从而有效地屏蔽长程力使其免于被探测到。这给例如 Eöt-Wash、MICROSCOPE 和月球激光测距(LLR)实验中的长程力搜寻带来了深刻影响。例如,我们发现当媒介子与中微子的耦合高于 $3\ imes10^{-10}$ 或 $5\ imes10^{-13}$ 时,分别来自 LLR 以及利用太阳作为吸引体的实验的限制将被完全消除。更大的耦合值也能显著缓解在更短距离下进行搜寻所带来的限制。

英文摘要:

Light bosons can mediate long-range forces. We show that light bosonic mediators interacting with a background medium, in particular, with the cosmic neutrino background (C$ν$B), may induce medium-dependent masses which could effectively screen long-range forces from detection. This leads to profound implications for long-range force searches in e.g. the Eöt-Wash, MICROSCOPE, and lunar laser-ranging (LLR) experiments. For instance, we find that when the coupling of the mediator to neutrinos is above $3\times10^{-10}$ or $5\times10^{-13}$, bounds from LLR and experiments employing the Sun as an attractor, respectively, would be entirely eliminated. Larger values of the coupling can also substantially alleviate bounds from searches conducted at shorter distances.
