Higgs-portal effective field theories are widely used as benchmarks in order to interpret collider and astroparticle searches for dark matter (DM) particles. To assess the validity of these effective models, it is important to confront them to concrete realizations that are complete in the ultraviolet regime. In this paper, we compare effective Higgs-portal models with scalar, fermionic and vector DM with a series of increasingly complex realistic models, taking into account all existing constraints from collider and astroparticle physics. These complete realizations include the inert doublet with scalar DM, the singlet-doublet model for fermionic DM and models based on spontaneously broken dark SU(2) and SU(3) gauge symmetries for vector boson DM. We also discuss the simpler scenarios in which a new scalar singlet field that mixes with the standard Higgs field is introduced with minimal couplings to isosinglet spin-\(0, \frac{1}{2}\) and 1 DM states. We show that in large regions of the parameter space of these models, the effective Higgs-portal approach provides a consistent limit and thus, can be safely adopted, in particular for the interpretation of searches for invisible Higgs boson decays at the LHC. The phenomenological implications of assuming or not that the DM states generate the correct cosmological relic density are also discussed.

希格斯门户有效场理论被广泛用作基准，以解释对撞机和天体粒子对暗物质 (DM) 粒子的搜索。为了评估这些有效模型的有效性，重要的是让它们面对在紫外线范围内完成的具体实现。在本文中，我们将有效的 Higgs-portal 模型与标量、费米子和矢量 DM 与一系列越来越复杂的现实模型进行比较，同时考虑到对撞机和天体粒子物理学的所有现有约束。这些完整的实现包括具有标量 DM 的惰性双峰、费米子 DM 的单峰-双峰模型以及基于矢量玻色子 DM 的自发破碎暗 SU(2) 和 SU(3) 规范对称性的模型。\(0, \frac{1}{2}\)和 1 DM 状态。我们表明，在这些模型的参数空间的大部分区域中，有效的希格斯门户方法提供了一致的限制，因此可以安全地采用，特别是用于解释 LHC 上不可见的希格斯玻色子衰变的搜索。还讨论了假设 DM 状态是否产生正确的宇宙学遗迹密度的现象学含义。
