AI 中文摘要
单重态-双重态费米子暗物质模型是一种经济的弱标度暗物质模型，通过与标准模型的电弱玻色子相互作用实现暗物质丰度。根据模型中汤川耦合的大小，暗物质遗迹丰度可通过退耦（含共湮灭）、共散射、退生或超弱相互作用重粒子（SuperWIMP）机制产生。我们分析该模型实现暗物质密度的方式，重点关注小汤川耦合区域：该区域直接和间接探测难度大，但可能产生丰富的对撞机物理现象。
英文摘要
The Singlet-Doublet fermion model of dark matter is an economical weak-scale dark matter model that realizes the dark matter abundance through interactions with the electroweak bosons of the Standard Model. Depending on the size of the Yukawa couplings in the model, the dark matter relic abundance can be produced via freeze-out (including co-annihilation), co-scattering, freeze-in, or the SuperWIMP mechanism. We analyze the ways this model can realize the dark matter density with emphasis on the small Yukawa coupling regime. In this limit, direct and indirect detection are difficult, but a rich collider phenomenology is possible.
