论文摘要
我们在一个模型中考虑了多组分的暗物质，其中一个暗物质成分在微弱的相互作用（FIMP）时，而第二个则相互作用（wimp）。该模型包含惰性标量双线和一个复杂的标量单元，并具有离散的$ z_4 $对称性。我们确定满足理论约束，撞机约束，遗物密度以及直接和间接检测限的参数空间。我们讨论了通过对撞机和天体物理搜索探测模型的可能性。我们发现，f夫可能形成主要的DM成分，在这种情况下，w imp的天体物理特征受到了极大的抑制。我们还探索了双重曲线可以腐烂成一对单元的情况，只剩下一个DM组件，即FIMP。这些情况受到BBN的约束，并且在山脉中最好探索，因为天体物理特征受到抑制。
We consider multi-component dark matter in a model where one dark matter component is feebly interacting (FIMP) while the second is weakly interacting (WIMP). The model contains an inert scalar doublet and a complex scalar singlet and features a discrete $Z_4$ symmetry. We determine the parameter space that satisfies theoretical constraints, collider constraints, relic density as well as direct and indirect detection limits. We discuss the possibility to probe the model through collider and astrophysical searches. We find that it is possible that the FIMP forms the dominant DM component, in this case the astrophysical signatures of the WIMP are much suppressed. We also explore the case where the doublet can decay into pairs of singlets leaving only one DM component, the FIMP. These scenarios are constrained by BBN and are best explored at colliders since astrophysical signatures are suppressed.
