Summary/Abstract: In the Standard Model of particle and fields, the non–zero Vacium expectation value of the Higgs field breaks the electroweak gauge symmetry, giving mass to the gauge bosons and elementary fermions. Its quantum is a spin–0particle, the Higgs boson: this scalar is the only missing elementary particle of this theoretical model. A brief overview of the searches for this particle performed in the last decades is given. In particular, the latest results of the search at the Large Hadron Collider are summarized and discussed, focusing on the recent observation by the experiments ATLAS and CMS of a new boson with mass around 125 GeV. Preliminary results based on available data show that this particle is consistent with the boson predicted by the Standard Model.
