论文摘要
我们研究了伪 - 迪拉克暗物质的最小模型，通过过渡电和磁偶极矩相互作用。氙气实验可以将电子检测到$ \ sim $ \，kev后坐力能量的启发，我们考虑了$ \ Mathcal {o} $（kev）群众质量特征之间的分布。我们通过冷冻机制研究了该暗物质候选者的生产。我们讨论了由较重状态的下散射产生的模型的直接检测特征，这些较重状态是在太阳能向前产生的，在基于电流和近XENON的直接检测实验中找到可观察到的签名。我们还研究了固定目标实验，Lepton Collider，Supernovae Coluting和Cosmology的互补限制。我们表明，最新的Xenonnt结果排除了这个动机良好和最小的暗物质候选者的参数空间的一部分。下一代氙气实验可以发现或进一步限制通过偶极矩算子可以相互作用的强弹性暗物质。
We study a minimal model of pseudo-Dirac dark matter, interacting through transition electric and magnetic dipole moments. Motivated by the fact that xenon experiments can detect electrons down to $\sim$\,keV recoil energies, we consider $\mathcal{O}$(keV) splittings between the mass eigenstates. We study the production of this dark matter candidate via the freeze-in mechanism. We discuss the direct detection signatures of the model arising from the down-scattering of the heavier state, that are produced in Solar upscattering, finding observable signatures at the current and near-future xenon based direct detection experiments. We also study complementary constraints on the model from fixed target experiments, lepton colliders, supernovae cooling and cosmology. We show that the latest XENONnT results rule out parts of the parameter space for this well motivated and minimal dark matter candidate. Next generation xenon experiments can either discover or further constrain how strongly inelastic dark matter can interact via the dipole moment operators.
