The existence of the Higgs boson was postulated more than 50 years ago, without any indication of its mass. The quest that followed, with several generations of particle physics experiments, culminated with the recent discovery of a new particle with a mass of 125 GeV. At least another half-century will be needed to map the properties of this particle with sufficient precision to understand its deepest origin.

L’existence du boson de Higgs a été postulée il y a plus de 50 ans sans indication d’un ordre de grandeur pour sa masse. La longue recherche qui s’en suivit, impliquant plusieurs générations d’expériences de physique des particules a été enfin couronnée par la découverte récente d’une nouvelle particule de masse de 125 GeV. Il s’en faudra sans doute de cinquante années supplémentaires pour en découvrir les propriétés avec une précision suffisante pour comprendre la profonde origine physique de cette particule.
