The Standard Model electroweak (EW) vacuum, in the absence of new physics below the Planck scale, lies very close to the boundary between stability and metastability, with the last option being the most probable. Several cosmological implications of this so-called 'near-criticality' are discussed. In the metastable vacuum case, the main challenges that the survival of the EW vacuum faces during the evolution of the Universe are analysed. In the stable vacuum case, the possibility of implementing Higgs inflation is critically examined.This article is part of the Theo Murphy meeting issue 'Higgs cosmology'.
在普朗克尺度以下不存在新物理的情况下，标准模型电弱（EW）真空非常接近稳定性和亚稳定性之间的边界，而最后一种情况是最有可能的。本文讨论了这种所谓“近临界性”的几个宇宙学含义。在亚稳真空的情况下，分析了EW真空在宇宙演化过程中面临的主要生存挑战。在稳定真空的情况下，对实现希格斯暴胀的可能性进行了严格审查。本文是西奥·墨菲会议特刊“希格斯宇宙学”的一部分。
