Summary
A general method for calculating the renormalization of partially conserved vector currents due to symmetry breaking is discussed. As an application, the renormalization of the strangeness-changing weak vector current is calculated in the pole approximation and its effect on universality is discussed.
Riassunto
In questo lavoro viene discusso un metodo generale per il caloolo degli effetti di rinormalizzazione per una oorrente parzialmente conservata. Come applicazione, viene calcolata, usando l’approssimazione a polo, la rinormalizzazione della corrente debole ohe canmbia la stranezza e se ne discute l’effetto per quel ehe riguarda l’universalità delle interazioni deboli.
