Après la découverte du boson de Higgs, le modèle standard de la physique des particules peut être considéree comme une théorie confirmée par l'expérience, potentiellement valable jusquà l'échelle de Planck et permettant de suivre l'évolution de l'univers depuis l'époque inflationnaire jusqu'à aujourdhui. Notre article discute les liens entre les résultats obtenus avec le grand collisionneur de hadrons (LHC) et l'inflation cosmologique. Nous résumons les propriétés des modèles de « Higgs-inflation » et leur relation avec la métastabilité potentielle du vide électrofaible. Une courte revue des limites de cette métastabilité dans les modèles d'inflation ne reposant pas sur le boson de Higgs est aussi présentée.

After the Higgs boson has been discovered, the Standard Model of particle physics became a confirmed theory, potentially valid up to the Planck scale and allowing one to trace the evolution of the Universe from the inflationary stage till the present days. We discuss the relation between the results from the LHC and the inflationary cosmology. We overview the Higgs inflation, and its relation to the possible metastability of the electroweak vacuum. A short overview of the bounds on the metastability of the electroweak vacuum in the models with inflation not related to the Higgs boson is presented.
