论文摘要
迄今为止，大多数搜索宇宙轴都集中在其冷藏物上，因为（一个组成部分）暗物质，但各种动机良好的宇宙学来源都会产生“增强”轴的“增强”轴，这些轴永远存在相对论。我们证明了现有的/即将到来的中微子实验，例如Super-Kamiokande，Hyper-Kamiokande，Dune，Dune，Juno和Icecube，可以探测这种能量的轴突遗物。特征签名是由轴 - 光子偶联诱导的轴突吸收的单能单光子信号。该提案旨在涵盖与现有斧头搜索互补的参数范围，并为中微子设施提供了新的机会。
While most searches for cosmic axions so far focused on their cold relics as (a component of) dark matter, various well-motivated cosmological sources can produce "boosted" axions that remain relativistic today. We demonstrate that existing/upcoming neutrino experiments such as Super-Kamiokande, Hyper-Kamiokande, DUNE, JUNO, and IceCube can probe such energetic axion relics. The characteristic signature is the mono-energetic single photon signal from axion absorption induced by the axion-photon coupling. This proposal offers to cover parameter ranges that are complementary to existing axion searches and provides new opportunities for discovery with neutrino facilities.
