Summary

We investigate a Lagrangian model ofSU 3 symmetry that is applicable to breakdown on a singular layer ofSU 3 octet space as well as on the general layer. In both cases, gauge particles corresponding to broken components of the symmetry acquire mass, while those corresponding to the little group of exact symmetries remain massless. We discuss the gauge-invariance properties of our model. including symmetry-breaking effects.

Riassunto

Si studia un modello lagrangiano della simlllctriaSU 3 , applicabile alla rottura tanto sullo strato singolo nello spazio negli ottetti diSU 3 quanto sullo strato generale. In entrambi i casi. la particelle di gauge. corrispondenti alle componenti rotte della simmetria. acquistano massa, mentre quelle corrispondenti al piccolo gruppo di simmetrie esatte restano senza massa. Si discutono le proprietà di invarianza di gauge del nostro modello, comprendente gli effetti della rottura della simmetria.
