Summary
The spontaneous breaking of chiralU 3×U 3 symmetry down toU 1×U 1×U 1 is studied from the in-field point of view. It is shown that the original symmetry undergoes a dynamical rearrangement and thus the observational symmetry,i.e. the symmetry of in-fields, assumes a totally different structure from that of the Heisenberg fields. As its application, the low-energy theorems are derived. The generalization of this method for higher symmetries is also discussed.
Riassunto
Si studia la spontanea rottura della simmetria chiraleU 3×U 3 fino aU 1×U 1×U 1 dal punto di vista dell'in-campo. Si mostra che la simmetria originale è sottoposta a un riordinamento dinamico e così la simmetria osservazionale, cioè la simmetria di in-campi, assume una struttura totalmente diversa da quella dei campi di Heisenberg. Come sua applicazione, si derivano teoremi a bassa energia. La generalizzazione di questo metodo per più alte simmetrie è pure discussa.
