Summary
It is shown that, in the noncovariant axial gauge, quark and gluon mass shell renormalization constants (if suitably defined) obey the classic Ward identity of quantum electrodynamicsZ 1=Z 2. Similar relations hold for the pure gluon sector. The validity of such identities in covariant gauges has been proven recently in the literature. The derivation in the axial gauge is considerably simpler than in covariant gauges.
Riassunto
Si mostra che nel gauge assiale non covariante le costanti di rinormalizzazione dello strato di massa del gluone e del quark (se definite in maniera adeguata) obbediscono la classica identità di Ward della elettrodinamica quantisticaZ 1=Z 2. Relazioni simili sono valide per il puro settore gluonico. La validità di tali identità nei gauge covarianti è stata provata recentemente nella letteratura. La derivazione nel gauge assiale è considerevolmente più semplice che nei gauge covarianti.
