In this work, we study multicomponent dark sectors comprised of a fermionic and a scalar dark matter candidate. In the scalar sector, we mostly focus on the Inert Doublet Model while in the fermionic sector we study three different models. For all of them, we investigate the impact that dark matter conversion and regular WIMP dark matter annihilating processes have on the relic abundance. We mostly recover the region between the electroweak scale and ∼ 550 GeV for the scalar dark matter mass, which is usually excluded in the Inert Doublet Model. We also consider current constraints from both direct detection and indirect detection experiments and include future prospects to probe the models. Additionally, we investigate constraints from collider searches on the fermionic dark matter candidates.

在这项工作中，我们研究了由费米离子和标量暗物质候选物组成的多组分暗区。在标量领域，我们主要关注Inert Doublet模型，而在费米离子领域，我们研究三种不同的模型。对于所有这些，我们研究了暗物质转化和常规WIMP暗物质an灭过程对文物丰度的影响。对于标量暗物质质量，我们通常会恢复介于电弱标度和550 GeV之间的区域，这通常在Inert Doublet模型中不包括在内。我们还考虑了直接检测和间接检测实验中的当前约束条件，并包括了探究模型的未来前景。此外，我们调查了对撞机搜索对铁离子暗物质候选物的约束。
