论文摘要
我们提出了$ n^\ prime $的新搜索，这是一种黑暗的巴里，可以与标准模型中子混合。我们表明，ISODAR是一项提议，将强烈的回旋子放置在大容量的中微子检测器深地下，可能会寻找$ n \ to n \ n^\ prime \ to n $ prienditions的转变，其背景比表面实验低得多。如果没有任何对实验的主要目标进行任何修改，就可以使用这种适当的中子般的直觉搜索，并将为$ n $ -n $ -n^\ prime $混合提供最强的实验室限制。我们还将深色中子视为暗物质，并表明它们在深层探测器（例如SNO和Borexino）中的核吸收是参数空间中一些最强的限制。最后，我们描述了其他$ n^\ prime $签名，例如中子闪闪发光，散布源，反应堆和超低中子的消失。
We propose new searches for $n^\prime$, a dark baryon that can mix with the Standard Model neutron. We show that IsoDAR, a proposal to place an intense cyclotron near a large-volume neutrino detector deep underground, can look for $n\to n^\prime \to n$ transitions with much lower backgrounds than surface experiments. This opportune neutron-shining-through-a-wall search would be possible without any modifications to the primary goals of the experiment and would provide the strongest laboratory constraints on the $n$-$n^\prime$ mixing for a wide range of mass splitting. We also consider dark neutrons as dark matter and show that their nuclear absorption at deep-underground detectors such as SNO and Borexino places some of the strongest limits in parameter space. Finally, we describe other $n^\prime$ signatures, such as neutrons shining through walls at spallation sources, reactors, and the disappearance of ultracold neutrons.
