论文摘要
我们提出了一个最小的紫外线完全模型，用于导致亚GEV热遗物的运动学禁止暗物质（DM）。我们至关重要的认识是，两-HIGGS-DOUBLET模型可以提供一个光中介器，DM可以通过该模型将其歼灭成Sm Lepton，从而避免间接检测约束。预计DM质量非常接近瘦素的质量，这可以从DM歼灭到伽马射线中鉴定出来。由于在重现DM遗物丰度时与MUON的相当大的耦合，因此该框架自然有利于$（g-2）_μ$异常的分辨率。此外，通过将这种设置嵌入ZEE模型中，我们表明中微子振荡的现象本质上与观察到的DM的遗物丰度相关。我们框架中涉及的所有新物理学都处于或低于Electroweak量表，使其在即将到来的山脉，束降低实验以及未来的Sub-Gev Gamma-ray望远镜上进行测试。
We propose a minimal UV-complete model for kinematically forbidden Dark Matter (DM) leading to a sub-GeV thermal relic. Our crucial realization is that the two-Higgs-doublet model can provide a light mediator through which the DM can annihilate into SM leptons, avoiding indirect detection constraints. The DM mass is predicted to be very close to the mass of the leptons, which can potentially be identified from DM annihilation into gamma-rays. Due to sizable couplings to muons in reproducing the DM relic abundance, this framework naturally favors a resolution to the $(g-2)_μ$ anomaly. Furthermore, by embedding this setup to the Zee model, we show that the phenomenon of neutrino oscillations is inherently connected to the observed relic abundance of DM. All new physics involved in our framework lies at or below the electroweak scale, making it testable at upcoming colliders, beam-dump experiments, and future sub-GeV gamma-ray telescopes.
