作为多组分暗物质的惰性双重态

Inert doublet as multicomponent dark matter

Amalia Betancur, Guillermo Palacio, Andrés Rivera

摘要:

在这项工作中,我们研究的多组分暗部门组成的费米子和标量暗物质候选人。在标量部分,我们主要集中在惰性双重模型,而在费米部分,我们研究了三种不同的模型。对于所有这些,我们调查的影响,暗物质转换和定期WIMP暗物质湮灭过程的遗迹丰度。对于标量暗物质质量,我们主要恢复了电弱标度和$\sim$ 550 GeV之间的区域,这通常被排除在惰性双重态模型之外。我们还考虑了直接检测和间接检测实验的当前限制,并包括未来的前景来探索模型。此外,我们调查的限制,从对撞机上的费米暗物质候选人的搜索。

英文摘要:

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 $\sim$ 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.
