The Higgs Boson and the Standard Model of Particle Physics,iginally postulated in the second half of the XX century, but experimentally detected only 50 years later. More details about the properties and the phenomenology of this particle at hadron colliders are given in Sect. 1.2. The chapter closes in Sect. 1.3, with the description of the Higgs boson dec
