Résumé
Abstract

La découverte du boson de Higgs à une masse proche de 125 GeV par les expériences ATLAS et CMS auprès du collisionneur LHC en 2012 a redéfini le paysage de la physique des hautes énergies. L'analyse de l'ensemble complet des données collectées en collisions pp à des énergies dans le centre de masse de 7 et 8 TeV a permis des progrès considérables depuis la découverte. Une revue des derniers résultats est présentée.

The discovery of the Higgs boson at a mass around 125 GeV by the ATLAS and CMS experiments at the LHC collider in 2012 establishes a new landscape in high-energy physics. The analysis of the full data sample collected with pp collisions at centre-of-mass energies of 7 and 8 TeV has allowed for considerable progress since the discovery. A review of the latest results is presented.
