Geometrodynamics for quarks and hadrons: The definition of currents

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

We show that the naive definition of the “direct part” of the vector and axial vector currents does not obey the necessary conservation conditions. The reasons for this failure are clarified and the precise conditions for restoring conservation are stated. Finally, an improved definition of currents is proposed and the physical interpretation is discussed.

Riassunto

Si mostra che la definizione più semplice di “parte diretta” delle correnti vettoriali e assiali non soddisfa le necessarie condizioni di conservazione. Le ragioni di tale occorrenza sono chiarite e si stabiliscono le condizioni precise per riottenere la corretta conservazione. Infine si propone una migliore definizione delle correnti e se ne dà un'interpretazione fisica.
