论文摘要
Sub-GEV热遗物深色物质通常需要存在光中介粒子。我们介绍了光线两-doublet门户，该门户用最小的UV-Complete模型进行了sub-Gev暗物质的最小模型，并将运动员禁止歼灭到瘦素中。在这种情况下，所有新物理学都在电动量表上或低于电动量表，影响了希格斯物理，若恩异常磁矩和潜在的中微子质量。通过未来的MEV伽马射线望远镜观察辐射性暗物质歼灭将是明确识别情况的关键。
Sub-GeV thermal relic dark matter typically requires the existence of a light mediator particle. We introduce the light two-Higgs-doublet portal, illustrated by a minimal UV-complete model for sub-GeV dark matter with kinematically forbidden annihilations into leptons. All new physics states in this scenario lie at or below the electroweak scale, affecting Higgs physics, the muon anomalous magnetic moment and potentially neutrino masses. Observation of radiative dark matter annihilation by future MeV gamma-ray telescopes would be key to unambiguously identify the scenario.
