On a full geometrization of conservation laws in Gürsey’s formalism

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Gürsey’s equations for the nucleon are investigated. Besides the generalized Pauli transformationsC′ a second transformation groupC″ is introduced. From the unitary parts ofC′ andC″ anE 4-isospace is constructed. Isotransformations leave the conventional commutation relations invariant. It is shown that the baryon number and charge conservation laws are generated by rotations inE 4 and the isospin-vectorI belongs to the (1, 2, 3) subspace ofE 4.

Riassunto

Si esaminano le equazioni di Gürsey. Oltre alle transformazioni di Pauli generalizzateC′ si introduce un secondo gruppo di transformazioniC″. Con le parti unitarie diC′ eC″ si costruisce un isospazioE 4. Le isotrasformazioni non modificano l’invarianza delle relazioni di commutazione usuali. Si dimostra che le leggi di conservazione del numero di barioni e della carica sono dovute a rotazioni inE 4 e che il vettore di isospinI appartiene al sottospazio (1, 2, 3) diE 4.
