论文摘要
我们提出了简单的场景，其中Lepton风味侵略耦合通过在几个KEV范围内的质量冻结轴粒子来产生观察到的暗物质丰度。与风味 - 基因冻结相比，该机制增强了暗物质稳定性，软化恒星冷却限制并提高了基于加速器的搜索的实验灵敏度。这些情况可以通过未来的X射线望远镜进行测试，在某些情况下，几乎可以通过在MU3E和MEG II等高强度实验下对Lepton侵犯的新搜索进行探索。
We propose simple scenarios where lepton flavor-violating couplings generate the observed dark matter abundance through freeze-in of an axion-like particle with mass in the few keV range. Compared to flavor-diagonal freeze-in, this mechanism enhances dark matter stability, softens stellar cooling constraints and improves the experimental sensitivity of accelerator-based searches. These scenarios can be tested by future X-ray telescopes, and in some cases will be almost entirely probed by new searches for lepton flavor violation at high-intensity experiments such as Mu3e and MEG II.
