The discovery of the Higgs boson has opened a new avenue for exploring physics beyond the Standard Model. In this review, we discuss cosmological aspects of the simplest Higgs couplings to the hidden sector, known as the Higgs portal. We focus on implications of such couplings for inflation, vacuum stability and dark matter, with the latter including both the traditional weakly interacting massive particles as well as feebly interacting scalars. The cosmological impact of the Higgs portal can be important even for tiny values of the couplings.

希格斯宇宙学门户

希格斯玻色子的发现为探索超越标准模型的物理学开辟了一条新途径。在这篇评论中，我们讨论了与隐藏扇区（称为希格斯门户）的最简单的希格斯耦合的宇宙学方面。我们关注这种耦合对暴胀、真空稳定性和暗物质的影响，后者包括传统的弱相互作用的大质量粒子以及弱相互作用的标量。即使对于很小的耦合值，希格斯门户的宇宙学影响也可能很重要。
