论文摘要
搜索类似轴突的颗粒（ALP）是由粒子物理学中强大的CP问题和天体物理学中无法解释的暗物质的动机。在这封信中，我们使用ISODAR以ISODAR为例，使用单核去激发光子进行了新的ALP搜索。我们表明，ISODAR可以设置使用ALP-PHOTON耦合在传统QCD轴上搜索中缩小差距的极限，并在模型中对新参数空间的大区域提供敏感性，在该模型中，阿尔卑斯山夫妇对核和电子。我们还展示了如何将同位素衰减实验设计以提高潜在的ALP产生并优化检测灵敏度。
Searches for axion-like particles (ALPs) are motivated by the strong CP problem in particle physics and by unexplained dark matter in astrophysics. In this letter, we discuss novel ALP searches using monoenergetic nuclear de-excitation photons from a beam dump, using IsoDAR as an example. We show that IsoDAR can set limits that close a gap in traditional QCD axion searches using the ALP-photon coupling, as well as provide sensitivity to large regions of new parameter space in models where ALPs couple to nucleons and electrons. We also show how isotope decay-at-rest experiments may be designed to improve potential ALP production and optimize detection sensitivity.
