Gell-Mann in Gell-Mann & Ne'eman Eightfold Way (1964) We attempt..to treat the eight known baryons as a supermultiplet, degenerate in the limit of a certain symmetry but split into isotopic spin multiplets by a symmetry-breaking term. 1977 Dædalus Summer 29 As a result of this symmetry-breaking, the quanta of the weak interactions are predicted to acquire a mass approximately forty or more times heavier than that of a proton. 1981 Nature 10 Dec. 522/1 The usual analogy used for spontaneous symmetry breaking is ferromagnetism. Maxwell's equations are rotationally invariant; however, below the Curie temperature the rotational invariance of a ferromagnet is spontaneously broken when the magnetization chooses a specific direction. < as lemmas |
