Summary
The extent to which PS(PS) meson theory is compatible with the almost conserved current hypothesis is examined. It is shown that a well-behaved almost conserved axial current cannot be constructed for PS(PS) theory. Nonlocal almost conserved currents are introduced which appear to satisfy the almost conserved current hypothesis for matrix elements not diagonal in the energy momentum.
Riassunto
Si esaminano i limiti entro cui la teoria del mesone PS(PS) è compatibile con l’ipotesi della corrente quasi conservata. Si dimostra che non si può costruire una corrente assiale quasi conservata di comportamento adatto per la teoria PS(PS). Si introducono correnti quasi conservate non locali che sembrano soddisfare l’ipotesi della corrente quasi conservata per elementi di matrice non diagonali nell’impulso-energia.
