[Brisure spontanée de symétrie]
Le concept de brisure spontanée de symétrie est présenté dans le cadre des symétries globales en physique de la matière condensée et en physique des particules. Ce concept est adapté ensuite aux symétries locales en théorie des champs relativistes. La présentation est centrée sur l'analyse conceptuelle qui conduit d'une part au vide dégénéré de la symétrie brisée globalement mais d'autre part à son invariance de jauge en présence d'une symétrie locale (dite de jauge).
The concept of spontaneous broken symmetry is reviewed in the presence of global symmetries both in matter and particle physics. This concept is then taken over to confront local symmetries in relativistic field theory. Emphasis is placed on the basic concepts where, in the former case, the vacuum of spontaneous broken symmetry is degenerate whereas that of local (or gauge) symmetry is gauge invariant.
