The discovery of a Higgs boson by the experiments at the Large Hadron Collider (LHC) in 2012 is a major milestone for particle physics. The discovery and the first determination of the most important properties of this boson will be reviewed. With the discovery of this new boson a new window of exploration of fundamental interactions is now available. This entails exploring the couplings of this Higgs boson with particles in the Standard Model and the search for new bosons. The status of the coupling determination will be reviewed. Results from searches of new bosons will also be summarized. In particular, the compatibility of the data with a potential new boson of a mass around 270 GeV and the consequences for phenomenology at the LHC will be discussed.
